Relay dev and small scale operator here Sir. I'll keep doing my thing and other relay devs can keep doing theirs. My only ask here is to make sure that NIP-44 can work in block mode for the folks that actually don't want to be constraint by unwritten limitations.

Fiatjaf has a change to nip44 to do this, but nobody has coded it yet. https://github.com/nostr-protocol/nips/pull/1907
If it's on Khatru then it has already been adopted by several relays :).

Unfortunately not on go-nostr yet. https://github.com/nbd-wtf/go-nostr/blob/master/nip44/nip44.go#L68-L70, but assuming that folks don't backport this, it is just a mater of time until Khatru relays migrate to nostrlib. So, what, at least 10% of relays out there will work fine.
