What is the point of making the max/min size just "preferred"? What are
the use cases when compositor should ignore the hint?

I suppose one would be when a client sets a relatively small max size,
but then asks to be maximized or fullscreened, forcing the compositor to
ignore the hint, but then, why would that client ever set the relatively
small max size if it wasn't any truth to it?
