@Xavier: some historical background: with the move from qt4->qt5 even
simple plugins written for both python2 and python3 could not be run in
both QGIS/Qt versions because there was always this

from PyQt{VERSION} import QtX

in the Plugins

By abstracting out the version we 'hide' this and make an upcoming Qt
upgrade easier.
It was also possible to fix some things in between.
