(After switching from qt-copy to kde-qt yesterday, I had another look at 
this also...)

Two of my machines (the two I build KDE on, in fact) are still F10, 
which currently only has 2.0.0 available. If it's removed, I'll probably 
end up rolling my own copy of dev as if I'd checked out kdesupport/eigen 
(except from the actual upstream, of course, but building/installing it 
the same way as kdesupport).

That's not a problem (for me, anyway), just something to consider.

Personally, I'd appreciate this as a stopgap. Not sure though if there 
are issues it could cause.
