That’s part of the problem with how Emacs deals with GTK, it does many
things the X way rather than the GTK way.

For example, mouse and keyboard events are dealt with using X code,
but GTK provides it’s own APIs for dealing with them. I thought
implementing touch events would be easy because GTK already does all
the heavy lifting, but Emacs doesn’t use GTK for events.

I strongly suspect a Wayland compatible GTK Emacs would have to remove
a lot of (all?) X code and replace it with GTK code.

I don’t think I understand the difference.
