I don't get why "new" things always have to "replace" the old, tried and tested, things. Can't they co-exist? Install and use Xorg if you need remote access or a more "traditional" Windowing system. Use Wayland (or something else) if you want a fancy desktop for games and 3D graphics. The both serve different purposes and I believe it would be bad to try and combine everything into a "single" application that can do everything.
