Libraries don't call QCoreApplication's constructor.

The application may have been recompiled and thus will inform QCoreApplication 
it was compiled against 6.4, but the library in question (a KF6 one) may have 
still been compiled against 6.3.

Wrong tool for the job, as explained above. Removing in:

In any case, I'll not make a runtime decision based on version. It's much 
easier to make a static decision based on which function you called.
