I do find the lack of acknowledgement of mini-roundabouts by routers a strange
omission.
They just need to say Turn left/turn right/go straight on at the
mini-roundabout the same as a human passenger does if they are giving
directions. In terms of on-screen directions just use the normal turn arrows
with a blue mini roundabout sign in the middle.

I'm not sure I understand why there is any confusion. They are traversable.

Not sure about diameter, that implies something is round. The paint usually is,
but the area around it very rarely is.

Why? Mini-roundabout is the standard name everyone knows, it's not just an OSM
tag. If I told my girlfriend to turn right at the traversable roundabout she
would be very confused.
Drawing a roundabout way in the space would usually be challenging, many you
wouldn't attempt to go around.
