Yeah, they should have removed the DM Relays they added on the nip-17 client. This can happen in many nostr features if the user just deleted the client that supported them without telling the network to revert back to the older standard. The NIP itself prescribes that behavior of going for nip-17 if DM relays are set.
Discussion
My recommendation here is to keep a nip-17 client available just for chat and really avoid using the old standard nip04 that leaks metadata everywhere.
There are bad actors in Nostr trying to track and break those nip04 DMs.
Well, you did recently add a spot for pronouns, what if you added a spot for signal username (or simplex link) ?
Could be combined with an auto response to nip04 dms to message the person on signal instead? Idk just spit balling a feature idea
Same thing could happen. The user could set that up and then uninstall Signal/SimpleX and never see your message.
We may add yet another preference per user to keep on nip04 after you disable it. But since many nostr clients are now deleting nip04, the opposite can also happen. Your friend could delete primal and then not see any of your nip04 messages in a new client.
Maybe. This has me thinking... Is there currently a way on nostr to upvote issues and such?
It definitely requires some thinking through the implications, but having ability to associate WhatsApp, Signal and Simplex could be quite interesting. All latin America runs on WhatsApp and a lot of privacy afficionados run on Signal...
