+1 from me for "utter embarrassment".
A slight tangent, perhaps we should be less afraid of making behavioural changes to Qt in minor releases, as long as they are flagged and old behaviour can be restored. The flags could serve for say 3 minor releases and then be retired together with the old code path. An even softer path could be to make changes opt-in, then opt-out, and finally mandatory over the course of several minor releases.
