Comment (by RJVB):

 I'm not so sure, I think it's a good idea only if we can indeed upgrade
 all PortGroup qt5 statements ourselves (well, you, evidently).

 If not, the problem with this approach is that it is likely to shoot us in
 the feet w.r.t. the drop-in replacement nature of qt5-kde. We're seeing it
 with cmake-1.1 already: what's the adoption rate of that? Of course that
 file is still in flux, but concerning new features that won't change
 anything for ports that don't require them.
 I'd hate to end up in a situation where we're told that we just have to
 provide our own PG and probably install qt5-kde in parallel.
