That's the only hard and fast distinction between mini and regular
roundabouts.

I'm sure there's probably some more-way mini-roundabouts somewhere, just as
I've been through intersections that probably should have been quite a
large roundabout but instead ended up as an 8-way traffic control spaghetti
bowl of turn restrictions, physical islands, priority signage and traffic
lights.  So I wouldn't consider this as a defining or exclusionary
characteristic one way or another.

Right, because it, effectively, is a mundane junction, just being smarter
about it than an all-way stop and more likely to get pedestrians safely
across the junction than an uncontrolled junction.
