The crux here is there is no mechanism for all these "I wishes" and "we shoulds" to become nostr-reality. The cut of for a single person or group with lots of time and energy to lobby everyone else in the network and eventfully get something implemented to a degree that we might call "protocol-wide" was around two years ago. Now it's effectively impossible, window's closed (as it always does with no governance).
The best we can hope for is window-dressing, thinks like follow packs and such, definitely not "spec", and even then spotty coverage at best.
We started with signed JSON events on websocket relays (all of which are existing protocols) then we added this Nostr social protocol, and now it's so fractured that we're sort of back again to signed JSON events on websocket relays, except with some residual social, so what you might call signed JSON events on websocket relays plus plus.
