The probably most important module - Qt/Widgets - sits on a graphic 
stack, that had been identified as not being competitive many years ago. 
The only reason why the module ( = Qt on the desktop ) remains 
competitive is the lack of competition - including Qt/Quick modules.

My expectation for a major release like Qt6 would be to see Qt/Widgets 
being migrated to the newer graphic stack - even if this would result in 
substantial API incompatibilities.

Actually each major release should have a story, that has to do with 
some sort of innovation that might require to remove old stuff. But Qt6 
does not seem to have something like this and why is it necessary then 
f.e to remove deprecated/failed modules like QC1 ?
