One additional note on that, I was initially worried about which use
cases were going to be broken by these changes. Then I realized that the
very same use cases would be broken when using wayland (after taking into
account Jakub's comments). Since this potential breakage will happen
anyway whether we want it or not, it's not going to make a big
difference if we do the same when running on  X11.
