It will not affect Wayland at all, since the Wayland drag-and-drop API
is too limited to allow Emacs to implement drag-and-drop properly there.

Most importantly, there is no way to cancel drag-and-drop after it
begins (think C-g), or to receive a notification when the pointer
reenters the frame where it originated after leaving.

X will probably remain the primary window server for the next decade or
so.  Anyone who doesn't want to use one of the several Wayland-ready
desktop environments on supported hardware will have to use X, even if
Wayland is the default on most distros.
