Summary:
Currently, if a script relies on clientAdded to setup some required
connections, then it probably won't work with Wayland clients because
clientAdded is emitted only for X11 clients.
Test Plan:
* Installed sticky window snapping script, it works;
* Installed a couple of tiling scripts, with some small changes, they work.
