I often switch between Wayland and X. My only concern is java does not yet support Wayland and old native libraries (e.g. 3D stuff for no longer maintained Java games) will probably break, once Java actually switches. Java and some Java games work with the xwayland compatibility layer, for now, but there are glitches sometimes. There are multiple projects porting Java stuff (e.g. Swing) to Wayland. All unofficial and incomplete.
