I would argue that libraries have an additional problem in that there's a many to one relationship between users and maintainer. It feels like there should be a way to design the ecosystems so that the maintainer doesn't end up with so much default expectations.

I think a more generalized version of OP's concept goes into a lot of things.

I thought about this when I first played Minecraft on a multiplayer server where people had vandalized the world. Much harder to keep it tidy than making it ugly. I think they usually solved this by giving mods ability to rewind. Crude but effective.

Like, what makes Wikipedia work? It's easy to go back in the version history when somebody breaks stuff?

It looks like there should be a bunch of tricks that could be used to design these systems so that doing the right thing is easier than breaking stuff.
