They do, if you subscribe to the GitHub nips repo as the arbiter of truth. Meaning you trust the group of folks who have merge powers to make decisions you find reasonable and don’t break your client (which have happened). There’s already attempts to decentralize the NIPs repo by using Nostr as the mechanism to decimate spec updates. So you could have dozens of different specifications for the same concept / NIP. You could even introduce a NIP number where the spec has nothing to do with the same NIP number in the GitHub repo. There would need to be a way of specifying in the published event which truth it subscribes to. Or not, and we just plow through this chaotic decentralized environment and hope everything works out. 😅 

 Made a typo. I didn’t mean decimate. I meant disseminate. 😂
