Yes I think my questions were also asked and answered (mostly) in 
another thread of this email. It sounds like "removing a role" is not 
actually something that happens.

I feel that destroying the role object should not have any effect. So 
destroying the xdg_shell_surface would not change how the surface is 
displayed. The client could create a new xdg_shell_surface object and 
continue manipulating the surface with it.

The reason is that it seems very inconsistent with the ability to create 
more than one instance of the same role object. Now destroying all 
except the last one has no effect, but destroying the last one does?
