a similar idea was the original thought behind wikifreedia.xyz

what "nostr" means might vary for different developers

I had originally thought of the idea that ended up as wikifreedia as an editor where you could define what each NIP is, and, even if we got to have competing NIP implementations, at least the competing proposals could be documented.

Sort of like what you have with the DIPs repo, where stuff that wasn't "accepted" into the nips repo can (and does) still exist and be easily documentable/findable.
