maybe. a lot of people seem to complain about protocol level design choices made that make it unattractive to wider development. there are definitely people working on nostr things, but I don't know of anyone working on what you call the relay-finding problem. 
Seems like something worthwhile

This isn't a criticism of nostr, but rather of its development priorities.  It seems really weird to me that the decentralized relay-finding problem isn't even acknowledged.

> this problem gets avoided by most people being in the same handful of relays

Isn't that kind of centralization the exact opposite of what nostr is trying to achieve?

i have an npub.  how am i supposed to find the relay?

These are still very early days, so I don't think it's fair to paint with such a wide brush. Currently this problem gets avoided by most people being in the same handful of relays.
