 > Yes, there seems to be little benefit to using Qt4 when Qt5 alternatives
 are available, but KF5 never made it into the tree and the KDE4 ports
 mostly (still) work just fine so there's that. (I'm still using KDE4's PIM
 myself, for instance.)

 KDE4 is totally broken, AFAIK, due to a broken `soprano`, which is
 required for nearly anything.
