the more pragmatic approach is to "hide" the qt6 variant behind ifdefs.

in fact, the introduction of a respective configure feature (so you
would #if QT_CONFIG(qt6)) has been on the table for quite a while
already, but nobody pushed for it yet, presumably because we haven't
officially started qt6 yet.

note that the qt(core) code is already full of QT_VERSION_CHECK(6,0,0)
which does effectively the same, but to activate it you would need to
change .qmake.conf instead of just calling configure -qt6.
