No, the reason is that flags() are not used for header data items, so
the headerview doesn't know that its items are checkable.

Quite frankly I can't think of any application right now that I've ever
used that had checkboxes in the header. So personally I'm not surprised
that Qt Model/View doesn't support this out of the box.
