I get what you’re saying.
In theory though there are 2 things I consider.
1 is that as far as I remember NIP-01 is all you need to qualify as Nostr. Whether that’s still true I’ll leave to others to weigh in.
The other is that the NIP repo only has as much authority as clients and relays give it. I mean you COULD do your own thing, with its own set of problems.
I think this model is good enough and maybe it just hasn’t been stress tested enough. Maybe corporate interests would be that stress test if and when they come in and try to embrace and extend something.
