I see a different intersection.  My Git NIP predates NIP-34 and I've been iterating on it 4-5 years until it's exactly what I want.  However I can use git with ngit becasue its compatible with git.  Just like I use it with radicle.  In this case the common territory is git and nostr.  Rather than a bespoke NIP.  One thing that i need is the equivalent of "github pages" and radicle has implemented that, as have I.  If I used ngit too, that would be the first thing that I would look at.
