Ive built and open source P2P chat without back end

Is this even something people want? A friend and I built a fully secure p2p end-to-end encrypted chat messenger with groups 1:1 chats and calls, every message is fully encrypted and sent directly to the other person. The only backend existing is a directory server which lists users by their public id (the fingerprint of a Ed25519/Curve25519 keypair) and name. There is also a relay which is only used tho if the user is behind a NAT, or firewall.

More infos and the src is here https://github.com/Emn4tor/Seal

Is this project like even needed or is it something that ive built for fun and can leave alone, does anyone see a real use case for this?
