Consider deprecating the crate #317
Description
Relm is depending on the gtk crates. However they are unmaintained. New versions have been published that warn users about the deprecation, the Github repo has been archived and a Rust advisory was posted (gtk-rs/gtk4-rs#1935). It might make sense to also deprecate the relm crate, since the foundation it is built on is now unmaintained. I also did the same for my crate (https://crates.io/crates/gtk-layer-shell), that depends on gtk. It's best to close a project when it fulfilled it's purpose.
