I have never received a clearance for just "VFR On Top" without further
restrictions, although I understand it is permitted. Restrictions can be
"Maintain VFR On Top at or below xxx", "....at or above xxx", or "... at
or between xxx and yyy".

I understand that the controller is not responsible for separation, so I
wonder why I always get an altitude restriction, usually "at or below".


Do you receive these restrictions after reporting VFR-on-top? Are you
operating in airspace where ATC provides separation to VFR aircraft? Is
Special Use Airspace a factor?
