In theory. In practice, every app is designed for X11 or Wayland, building your own means you need to follow what most people use anyway if you want to have any working app on your system, or rewrite every app yourself

5-10 years ago there were no apps designed for Wayland. If you build it they (app developers) might actually come!

yep, that's why I stuck with x11, as it still does everything I need it to do. it's actually never crashed since they stopped fixing it.
