Thought about doing something like that myself but
1. time is limited and I really could need only 2 pairs or so
2. properly soldering those ICs at home isn´t too trivial although one could even use thermal epoxy for the power pad
3. if you have the space and don´t need "retrofittable"/LM3x7-compatible you can always jump for a denoizer solution of which there are many freely available PCB-designs
I guess guys like Prasi could do such a layout in a heartbeat.
Ideally even offered at the diyaudio-store fully populated.
There are solutions though that you can buy if you don´t need many.
Not too cheap but then the main components aren´t cheap either and even the offerings at Aliexpress aren´t any cheaper.

If you can do without "retrofittable"/LM3x7-compatible I like these boards which uses those devices in parallel for higher currents and the boards are tiny.

Where did you find those regulators from the picture?

I did do a google some time back - busy same result as you, most places out of stock or really crazy prices.
looking for a low noise supply for PGA2310 since I was seeing some difficulties in getting the same package of 317 and 337 on the regular major distribution sites
Did find some other LT chip but it’s midnight here and too sleep to check up it’s prices and availability.
In the meantime the use of the LT3042 resp. LT3045 seem to have popularized.
However, for the negative versions, like LT3090 or LT3094 hardly any pcb designs have yet emerged.
A pcb design for a dual version with for instance LT3032 may serve quite a few diy applications.

This is a great chip, I am commenting just from how the pin are layed out.
Soldering for me is also going to need some work around. But for my PGA2311 Board I do see my self re doing the power supply section from LM317 and 337. I used the Elektor’s old design where they use a small transistor. I think the article was on a pre amp with multiple opamps
