Looking at the NIS4461, this is something that really should be done at the source ideally, right? Adding one of these per feeder is quite expensive and probably not worth it, given that the only benefit would be per feeder fuse funcionality. From what I can tell, regarding inrush current, softstart etc. a single device on the source of the power bus would be totally sufficient.
What about just adding a small fuse board between the motherboard and the IDC feeder bus as a fix for now? Ideally this would later be added to a new mobo revision, but this might be an easier and more cost effective fix for the people having inrush issues than shipping new power supplies to them (which might or might not solve the problem reliably).

Description
Reconsideration of the whole power subsystem.
Suggested Solution
I did a quick design review, and I've found some (possible) issues. Some of them have already been pointed out, some are still hidden.
My recommendations are:
@sphawes I can elaborate a bit more about all of these features if you're interested.
As I'm planning to build a set of feeders for myself, I will implement these anyway. My plan is to do that later this summer. Unfortunately, KiCad projects are not easily mergeable ... BUT if I get a message that You're interested in these changes I Can calculate all components, draw schematics and update PCB ASAP then create a pull request.
Best Willy.
