Of course, this could be done in the client library as well. 2) Virtual roots allow the server to optimize batches of moves/unmaps/etc. Perhaps we could also do this by defining the semantics of a window group more precisely... 3) Virtual roots allow interesting manipulations of stock applications which do not understand more complicated multi-window paradigms. 4) Virtual roots are a very interesting technology for doing shared-X kinds of work.
