That is, as long as continuing to support Qt4 is not too much of a hassle, we might as well do it, but if it becomes a burden (and, in particular, if it starts to get in the way of usability improvements), I wouldn't have too many qualms about dropping it.

Many Slackers use -current (where Qt5 is available), and for those that still use 14.2, they have other problems – such as the fact that they are basically stuck with GnuPG 2.0…)

Macosx also relies on it until 2 revs ago  - though that is not far of of going qt5 now as apple eols sometime later this year.
