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.
