You are completely right, you would be relying on an implementation
detail that in principle could change in future.

However, that's an area that hasn't changed for ages, the overall layout
probably not since Qt 2(!). I don't think this is likely to change.

Sure, a dedicated QToolButton* QTabWidget::leftScrollButton() would
be more convenient for you.
