Yeah. That’s where I want to go with Haven as well. Having a nice, private UI where you can say:

* This person is trustworthy; let their followers write to my relay.

* This person? I don’t know. If three other folks follow them, then let them write to my relay (default).

* This other person? I love them, but they follow bots and weird people, so their follows don’t count when deciding if someone can write to my relay.

This is all "private" and local.

I’m currently running a private fork of Haven with a barebones implementation of this. No UI, just local files with npub / trust-level pairs, and so far it’s sorta working for me.

It’s still essentially a dumbed-down version of PGP ownertrust, but (hopefully) something that can be done in a way that’s more intuitive and attractive to normies than the whole PGP “signing key party” stuff.
