Yes, but doesn't desktop-shell need to be aware of these new layers?

For example, when the screen is locked, desktop-shell hides the layers
it knows about and shows the lock layer. If my plugin invents a new
layer and hooks it up, desktop-shell will not know anything about it
and it will not be hidden when the screen is locked...
