I think the same but I might be missing something too, it's kinda late and I'm tired. I fail to see why we need a new spec when NIP-29 has everything needed to make a Discord-like client.

The moderation primitives are optional, if your relay doesn't support NIP-29 you can still have unmanaged groups/channels and handle read and write access at the relay level.

I hope I'm wrong but looks like a severe case of NIH syndrome.
