It all seems like a load of rubbish to me! Just read these "rules"! Is it any surprise that most pilots don't understand the rules - if, indeed, they are rules.
Certain postings have stated that VMC approaches can only be undertaken below 10,000 ft - not true. What if the flight is being carried out VFR? And it can only be carried out in Class D,E,F,G airspace. Not true: what if the flight is Special VFR?
Many VFR and Sp VFR flights are conducted above FL100 and in Class A airspace. You can't generalise on this issue. If you are referring SPECIFICALLY to aircraft on IFR plans, then these complex and extraordinary "rules" may be correct. But they are not correct in general.
