That looks very promising! However, we still need to address a couple of 
issues:

* QtWayland doesn't allow to use more than one shell integration plugin 
at a time. Things such as configuration dialogs and so on are backed by 
xdg_toplevel surfaces. On the other hand, panels and notifications must 
be backed by layer_surface objects

* The xdg-shell integration plugin must call layer_shell.get_popup in 
order to set the parent surface for a popup before the initial commit is 
performed; otherwise kwin will post a protocol error and plasmashell 
will crash

Sigh, the human memory sucks, 2 out of 5 stars, not good. I remember 
checking out the blog post and qtlayershell repo a couple of years ago 
and for some reason it slipped my mind when I was writing the email. :(
