Tobacco, wine, Tabasco sauce, cheese, Tea, Coffee, etc. are organic products, who have gone through a process, each factory has its own, aging does change product smell and flavour A LOT; genetics , ambient, soil chemistry, Sun intensity, humidity, ALL real factors which change characteristics in a very perceivable way, and which EASILY pass double blind testing any day of the week.
None of that applies in a capacitor.
You can´t measure both with the same ruler.
Under your system, flavourless 40% alcohol triple distilled can substitute any Whisky, Cognac, Kirsch; a 10mg nicotine pill can substitute any cigarette or pipe load, 50 to 100 mg caffeine crystals can substitute coffee or tea .... think again.
I've repaired many components with broken legs. When you deal with a lead potted in epoxy, you must at least have the same length as the diameter of original lead to solder onto. Film/foil caps are usually straight forward to repair if this happens, but something like a carbon element potentiometer becomes prone to degradation from putting too much heat into the crimped contact, which relies on pressure for connection to the resistive element (not a good design, even when its a brand new part).
Lots of older rack mount equipment with panel mounted pots are prone to broken pot leads if there's too much flex on the front panel from the weight of the chassis. Once the leads break off, the pot is junk. Even if you manage to attach new leads, there is a reliability issue down the road with pots becoming intermittent, probably from the previous stress leading to the lead failure.
Its a smart move to secure any heavy part with a dab or two of hot glue or silicone RTV onto the pcb if its prone to vibration. The reduction in microphonics with film caps in high impedance tube circuits makes this a necessity to start with.

Could be worse 😉
One of our major Beer brands, is made out of corn!!
Or at least 50/50
So legally it is NOT beer, definitely not by German purity laws.
Now there is something called "Prohibition beer" which was made out of corn, out of desperation.
Here it was made during WW2 since suitable grains were exported but then people got used to it and it stuck.
See American beer....carbonated corn derivative.
The bubbles are pressurized CO2, same as Coca Cola.
Europeans make fun of it...
The Lager and Pilsner processes use a barley / grain base, and natural fermentation under ideal conditions causes the bubbles.
Corn syrup, with gas added, hardly qualifies as beer.
And in India, we get super strong beer, with a very high alcohol content.

Back to topic, a pot is worth repairing, because it is now mostly difficult to obtain, and is a visible part.
Capacitors are relatively easier, and nobody will open the cover and say "The characteristic sound of (fill in the blanks) capacitors has been altered by you!'
And they are fairly cheap, a few dollars at most, mostly penny items.
If you consider tech wages at 125 USD per hour, that cap has cost $100 to repair, hardly economical.

The best beer is Ale made by Trappists IMHO. That said, I'll take Tsing Tao over most US made beer.
I wonder, do you get Canadian beer there in India?
And yes, the labour cost of repairing the cap is more than the cost of the cap so I suggested binning it and getting another one 🙂 I don't use boutique parts though. For me, a 25 cent Kyet cap sounds just as good as some 200$ fancy copper mondorf or whatever.
My state officially has Prohibition.
I don't travel much outside, and I don't drink alcohol, so ...
You can check on line liquor stores in Gurgaon and Hyderabad, they should have a big selection.
Mumbai is not so big on variety.
Canadian beer would be ten times the price of it in Canada, so a hard to sell item.
We do get an amazing variety in single malts... Islay Mist, Glenfiddich, Glenmoragie, even Platinum Label and Blue Label in Johnnie Walker.
Suntory, Jack Daniels, other Kentucky Bourbons, the odd other whiskies.
Brandy, also a lot of VSOP of French origin.
Rums, no, not popular in imports.
Gin, wine, liqueurs...again not much variety, though Kahlua and Tequila do sell in small quantities.
Other than French wines, we see the odd Riesling, no California or Australian.
Vodka, again, the local product dominates, imports are expensive.

First of all, I don't pay myself and second I own all the tools and supplies needed for the repair. The actual costs were about one inch of solder, a few grams of flux and about ten minutes of my time. And, besides having the crossover working in a very short, it feels good to succesfully repair things.
Nice, but please be certain to mechanically fix it well, glue itbdown or whatever, since your repaired joint is much weaker than the original one ... which already failed.
Ha ha! Well done on the repair. I take it the cap was one of the copper types?
The "why fix it when you can throw it away" comments are puzzling. Isn't this DIY?

The risk of damage was high, soldering close to the dielectric layers.
And failure could have damaged speakers, which is again an expensive event to happen.
So, my advice had this in mind.
Others also agreed.

Sorry, I just don't see the danger in tying to fix a cap with a broken lead. I've done it, it was worth it. Nothing used in a critical place like a HT supply or similar. Mostly just caps used for crossover prototyping, where the leads get bent a lot and sometimes break.
In that case, I wrap #22 around the stub and solder it. Most cases, there is just no point wasting time to fix a 25 cent part. As I said before, I don't use 200$ magic capacitors...
Obbligato Gold are a little pricey, for example a 10uF 630V cap is £22.13. Film/foil aren't cheap. But these aren't $200 caps.
EDIT: Not film/foil - they are metalized film. A 400V Solen runs about $10.50
