https://github.com/nostr-protocol/nips/blob/master/09.md nip 9, which most relays support, allows you to delete events.

Hmm,
It allows you to request events are deleted, which is subtly different.
Would be interesting if a client only allowed you to connect to relays that met specific criteria, eg support nip-09.
It’s quite possible for a client server to test all the relays it encounters and whitelist the ones that pass unit testing.
🤔
Maybe in the future?
