I've been tinkering on rnostr trying to implement some NIPs. What NIPs are you most interested in seeing first?

How are your deletions implemented?
Event deletions with a tags should delete all events that match the a tag until the created_at. That's broken in strfry.
On a more difficult track, we must find a way to implement SYNC. https://github.com/nostr-protocol/nips/pull/826
Most of the traffic when resuming a client can be resolved with a super basic SYNC process.
I see this relay does not take into account the created_at tag. While I'm not currently a maintainer it seems like a good first PR for me to tackle. Thanks for the info!
