Right away AFAIK we would lose DCOP integration, the window styles that
come with TDE, and the kcontrol integration.  Users can already run
different window managers (compiz anyone?) so I would say this decision
should be made on a per-user basis.  A set of instructions on the Wiki for
configuring a users' session to use kwin4 wouldn't hurt. ;-)
