QQuickView does something similar - It has an explicit ResizeMode. Anway, I would still really prefer us adapating to our current uses cases and making them work well instead of targetting everything when it complicates our code base.

I really want to allow extrenal resize.
The fact that QQuickView allows only one way or the other is a limitation i never liked, especially because making it work both ways, is not hard at all (and SizeWindowToRootItem is completely useless on desktop systems).
