I have never had such a radio dialog when requesting a transit of controlled airspace (as compared to requesting to drop off an airways IFR flight plan to VFR). I also have routinely received instructions to enter controlled airspace below the sector MSA without any question of me as to if I am IFR or VFR OCAS (but as I am not under RCS this isn't an instruction to descend as compared to an instruction to be at a level sometime in the future when I am about to enter controlled airspace).
I have also read of occasions where people have been instructed (for instance up North) to enter the LLR at 1500 when there is terrain between their current (OCAS) position and the LLR that is above 1500 ft.
