Well, I think it's the other way around -- a plugin may not be an xmlguiclient.
We have major issue with mainwindows already -- since one xmlguiclient can
be part of only one main window, if any plugin is xmlguiclient, then its actions
can be available in only one main window.

And if plugin cannot be xmlguiclient and you want to contribute actions via
xmlgui, it naturally means that a view should be xmlguiclient.
