In which case ATC would be in-situ to integrate the VFR with the IFR on the IAP.

Totally agree. In my humble opinion any pilot conducting a straight-in approach to an uncontrolled busy circuit is overly optimistic, or arrogant, or mad, or a combination of all three. In my humble time watching aeroplanes going round and round I have witnessed such behaviour on many occasions. Frequently it turned out that the PIC was a very experienced and highly qualified aviator who should otherwise be setting an example.
