One annoying issue is that on most clients you connect once using a bunker:// connection string with a relay address and then the app will just always only try that relay forever unless you logout and login again -- apparently.

Would be nice to have another relay list, like kind 10012, just for signaling relays that can be used in NIP-46 for each key -- and the signing device itself could update that so clients would pick that up.
And maybe another optional field in the NIP-05 JSON just for these relays too, for Pablo's flow?
