Touché, Paolo. You are probably right here, though there are still a couple
of unknowns at this point.

By "very short lifespan" I am referring to the next Mac OS (10.12?), which
not everyone will use. It is unknown at this time whether Qt4 can be made
to support it (maybe we get lucky again and it doesn't break Qt4 much
more). On the other hand, I still get requests to support 10.6 (from 2009)
for nightlies.

If we look at some basic Mac OS adoption trends by users [0], it is
apparent that they adopt the latest OS much more so than users of Windows.
However, it is unclear how much this reflects the general Mac QGIS user's
OS adoption rate (guessing it is roughly equivalent).

Basically, as Nyall has pointed out, something needs done for Mac ASAP, not
4 or 8 or 12 months from now. Towards a solution, I would like to start
providing a Qt5-based nightly for Mac (after 2.12 is released).
