My home base has a roughly East/West runway. All circuits are to the south of the field.
We don't mind aircraft arriving from the North positioning for a right base when it's a left hand circuit or a right base when it's a left hand circuit.
Just so long as they are sensible about it. It saves time and fuel.
It may seem to some that they are making a turn against the circuit traffic, but they aren't 'in the circuit' until they have established on final.

Who are "we" "not to mind" aircraft failing to comply with the rules of the air? I suspect that you might "mind" when you find yourself head on to a joining aircraft when on opposite base legs. That is a very dubious argument about not being in the circuit until on final - rule 12 refers to an aircraft
in the vicinity being required to make all turns to the left unless... . In the event of a collision, do you really think that any reasonable person would agree with your interpretation?
