Has anyone thought about introducing versioned NIPs? It’s sometimes hard to keep up with revisions to existing ones. 

 Keep track of incompatibilities post NIP revisions: https://github.com/nostrability/nostrability

@Little Mikey D breaking NIP list: https://github.com/mikedilger/nips/blob/breaking-changes-list/BREAKING.md 

 That is good! I think a dependency graph would be awesome too to see the relationship between nips
