1) Most standards don't need to be found by most devs because they don't use them. Nobody uses all of the NIPs, either, after all, and that effect is about to go parabolic. I think everyone just needs to sort of give up on spec management.
2) It's not impossible to find them. There is a list in the wiki for events or you can simply use elasticsearch on nos.today. Or just #asknostr. Make a DVM spec discovery tool.
3) You can see the events popping up on relays and just search for the ones that seems stick around for a while and add them to the list yourself. This is dynamic discovery and someone already built it.

4) I don't need an event to announce the event that I'm publishing on relays and writing about in the wiki and in articles and discussing in communities. That's the same event being announced like 50 times and would encourage people to reserve NUD numbers that they don't end up using, or having NUD numbers assigned to unpopular events, like we have with the NIPS. This creates an ID "honeypot".
5) We don't need the "NUD". We have our own prefix. It's obvious that it is a Nostr spec, if it deals with Nostr and is a spec.
6) Implementations should lead. Marketing is proof of work. The best implementation will get the most attention and their spec will float to the top of the wiki or dominate the timeline for the people interested in that topic, and become the de facto standard.
7) We publish our specs on the wiki or other long-form articles, give the event a searcheable identifier, and then we implement it and talk about it all on Nostr. That gives everyone enough opportunity to find it, who is genuinely interested.
