Comment (by RJVB):

 Hmmm, I'm only talking about issues in Qt itself, almost anything else (in
 dependents) is mostly due to those dependents not testing on or
 considering specifics on Mac. It's rarely a big problem to prove that by
 using an official Qt install (cumbersome as that may be).

 I also have spent uncounted hours figuring out things related to the Qt4
 -> Qt5 transition. That was a huge change, but not a very good example in
 this context. Projects have had a LOT of time transitioning to Qt5 and
 since 5.7 Qt has been relatively stable.

 But it's not a big secret that just using Qt means any software will run
 correctly on any of the supported platforms.

 Then again I'm using a patched Qt version that has the very specific aim
 to improve things in this domain, notably the behaviour of KDE software on
 Mac. A few additional patches that bring back 10.9-specific code aren't
 going to make a big difference. I've already been running the backported
 Cocoa backend (and Mac widgetstyle, as far as I use it) for about 2
 months. Remember, that code has been very well tested and isn't being
 removed because it's instable but rather as a bit of spring cleaning.
 Anyway, as indicated in my OP, I have no idea at this time how much of
 that cleaning has happened outside the Cocoa backend. The 5.9.0RC
 installer still worked on 10.9 and software built and ran until hitting
 one of the changes in the Cocoa backend.

 I do have a compelling reason not to upgrade as long as I'm not obliged:
 getting things to work as *I* want has become increasingly cumbersome with
 each new OS X version and it's never the appropriate moment to take a few
 weeks off to figure out how to get back to a state where I'm feeling at
 home and productive. With 10.9 I actually ran it in a VM for months until
 I felt the time was right to transfer things to a regular boot disk, but
 then I had Parallels at my disposal which made it relatively easy to run
 an OS X VM. I'm trying to figure out how to clone my install to an
 external which I can boot in VirtualBox (so at least technically I can
 also run it on a Linux host) but I'm not making a lot of progress there.

 Failure to backport Qt 5.9 will give me a lot more reason to upgrade.
