Maybe one aspect I would like to add: there is a lot of software, that 
has to be compilable with Qt 5 and Qt 6. Especially when your product is 
library you can't decide which version of Qt is going to be used in the 
application.

It would be good if this does not end up in a total mess of ifdefs.

My experience from the past is, that it takes years until the majority 
of the applications has upgraded to the next major Qt version - and 
probably only few applications will seriously try out Qt x.0 versions.
