I agree. there are 2 totally legit and important use case here:
1. they want to maintain an alternative authoritative codebase commit tip (traditional fork)
2. they want to discuss and share patches without repo owners involvement or without the desire to share an agreed upon code fork
how do we enable this without enabling a npub to create a repository masquerading as a popular other repository? we haven't had anything like that yet but it is somewhat enviable.
maybe encouraging making it clear in the name / description and a reporting mechanism like nip56?
