"ATC authorization for an IFR aircraft to operate in VFR conditions at any
appropriate VFR altitude.."

Yes, but the point I was making (from the original) was that VFR-OT would
be conduced in Class A.

Class A, AIUI, contains NO "appropriate VFR altitudes".

The first point I disputed, and the one that many responders seemed to
have missed, was claiming VFR-OT at 33,500 feet.

Below Class A, I'm sure we've all done VFR-OT.

Is all airspace at 33,500 feet Class A?
