This is incidentally one of those theories in need of a reality
check I was refering to.

The assumption is wrong, as proven by the example of Qt Creator.

After some initial effort to make it compile with Qt 5 at all
(mostly due to the modularization and the Gui/Widget schism) it
compiles rather nicely with Qt 4 and Qt 5 from a single code base
without much #ifdef hackery.

It is definitely maintainable in that form. Good old Qt stuff.
Create once, deploy everywhere.
