Tim said we get motion hints everywhere now anyway (though I can't see
where that is done in the code). See the last paragraph here:

It looks like gtk_widget_set_has_tooltip() doesn't set events properly
anyway - if the widget isn't realized and doesn't have a window it won't
set the event mask at all.
