It is wrong, but not totally. 4.3 is of course not a minor update, but
still we maintain backwards compatibility. It usually is possible, even
if it is sometimes more work for us ("compatVersion", upgrade paths),
and I would not start negleting this very important part of our job as
core developers. This is one part of TYPO3 that most people admire and I
certainly also cherish: Upgrading is "so easy". Even upgrading from 3.8
to 4.0 maintained backwards compatibility on almost every aspect.
