Yeah at first I was thinking discovery of endpoints for identity, for which it's pretty hard to disagree that PKDNS is a step up over free-floating metadata events. For nostr at this point I wonder how painful processing a list of carefully selected breaking changes (encryption type included) would be? Even just changing encryption and maybe transport, and leaving most everything else the same. My gut says nostr would bounce back pretty quick, given that so much of nostr a this point is nostr enthusiasts. Of course if it didn't bounce back that'd be a big "D'oh!" moment.

The other discovery seems like a problem that if you *genuinely* have it that's a good sign!
