Possibly in p2p for one, not on the positive board, but I haven't looked into it because I prefer this scheme, which is anti ground loop also:

Any generic green 3mm will serve you well. That question was for SSHV1 I assume.
This is different rectifiction layout that allows use of dual standard SSHV2?
No.
the dual secondaries of a transformer are isolated. They are not "correlated". The dual secondary transformer creates two independent supplies.
These two supplies are then connected at some common point.
Using two transformers, each with an isolated secondary, achieves the same dual supplies that can be connected at some point.

It would be better to continue the sense lines separately all the way to the load. The +ve Hot and -ve Hot are both shown separate. The +ve Cold and -ve Cold should be shown the same.
All to the better then because even single secondary spare transformers can be used. Although somehow I had this differently registered in mind, I hope its exactly the same as with a common primary as I have only seen it in builds. This uses more components, and losses are higher because of the extra diodes, but this scheme offers easier ground management. It's easier to keep the large charging current pulses away from the system ground.
I have tried, using my limited resources, to measure the difference between dual bridge PSU and centre tapped+single bridge PSU for an effect on hum and noise and rail ripple.
I cannot measure a difference.
The key word is ''easier'', if the system ground is managed already very well there will not be much to improve on.
For symmetric +/- with positives no. For more than one positives as positives yes.
