In the end, there needs to be a centralized standards repo. It can contain garbage that no one uses, but there needs to be one.

The BIPs repo for example, it is mostly impartial, and there’s lots of crappy proposals in there. But there’s also things like SegWit. 

 You’re probably right. In practice, centralization is how order is maintained. But it’s not easy to say “you’ve had your fun. decentralization ends here.” without coming across as an elite with “special” powers.
