We shouldn't be using any private headers from Qt,
and i'm not aware of any being used.

You definitely won't need a rebuild within the same
Qt minor version. eg Qt 5.9.3 -> 5.9.4.

The switch between Qt 5.7 -> 5.9 "in theory" you could
get away without a rebuild if the ABI doesn't change.

However it's between the minor releases that Qt deprecates
(but not removes) functionality, which is why the recommendation is
always to rebuild on a minor version change.
