Ey yes! still working, but i have not touched it since the beginning of the year when i released it, was a proof of concept, but some people were expressing their interest for the project, maybe one day i will have more time to put there and improve it.
Lowent interacts with relays as whatever nostr client does, in the proof of concept relays are hardcoded, but would not be very difficult to use nip65, or atleast be able to modify then. I dont know if this answer solves your question, feel free to keep asking 👌
