Some of the ATCOs here care to comment ?
AFAIK, other than in an emergency or if given as conditional ('cleared to land after the XYZ has vacated' - I get these quite often), once cleared to land, that's it.
From a practical POV there's also a big difference between canceling / amending a, say, transit through CAS clearance and doing same on short final where the a/c is configured for landing (and, of course, a go-around).
Btw, I have had these 'orbits' a number of times, but never, ever, at such a late stage.
