[Tagging] Deprecating mini_roundabout

[Tony OSM]

I think deprecating mini_roundabout is incorrect.

Near where I live in Chorley England a 3 way junction was converted to a 
mini-roundabout to equalise the flow of traffic. The space available 
made a build roundabout impractical, and traffic lights would have been 
overkill. It works. It is different on the ground that a built 
roundabout (tin of poured paint versus brick and kerbing). The map is 
appropriately different - mini-roundabout has its own symbol whereas a 
roundabout is sized to reflect its actual size.

Understanding of mini_roundabouts (how to build complex junctions) and 
their distinctiveness may be helped by viewing

https://en.wikipedia.org/wiki/Magic_Roundabout_(Swindon)

and its OSM representation

The nearby Drakes roundabout is a large roundabout identified only by 
its shape
