Most DEs are either already ported to Wayland (Cinnamon, Enlightment), have a porting in progress or plan to port it eventually.
For WMs, it is more uncommon since they're so coupled with X11 specifics that this makes porting harder. However I don't really think it is a problem, if you want to continue using your WM it is fine, it is not that X11 is going away either way.
