Not necessarily; a style could have on itself the "equivalent" of 
globalStrut. However QStyle doesn't seem to have the equivalent of 
sizeHint / minimumSizeHint, so widgets cannot delegate that calculation 
to the style (which may take into account its own globalStrut), and 
instead widgets have use globalStrut themselves...

So, what you're implying is: lacking a better QStyle replacement, and I 
strongly doubt we'll get one in Qt 6,
1) we need globalStrut,
2) we should fix all Qt's own widgets to honour it?

My 2 c,
