Feels like making a messaging app but "how messages are delivered and to whom is left to the user to implement".
I think "who and how someone is vouched" is like 99.99% of the problem and they haven't tried to solve it so it's hard to see how much value there is here. (And tbh I doubt you really can solve this problem in a way that doesn't suck.)
Probably the idea is to eventually have these as some sort of public repo where you can merge files from arbitrary projects together? Or inherit from some well known project’s config?
