Not to mention, it is the same duplicated situation with QPointF and
QVector2D already, almost in the same sense. I can just encourage the
collaboration more again. Build only your layer on top of what QtCore
already provides, so establish what it does not provide.

I mean, you do not always need a hefty math library for simple things.
I personally believe that the point classes make sense in QtCore.
