I think I would be willing to go with this solution. It seems the
people who actually have mini roundabouts around them are very adamant
about their meaning. While I don't really see harm in using it in
slightly different circumstances where true mini roundabouts don't
exist, I think putting junction=roundabout on nodes is acceptable as

the JOSM validator will need to be updated to allow this tag on a node
without complaining and not require a highway=* tag to go along with
it. Mapnik can probably use the same symbol for both. Anything else
need to change? (aside from the wiki of course)
