Yes. Although if we're trying to make our map data work with routers we
can't fix (eg, Garmin), then we're in an interesting situation.

("Don't use Garmin" is not an answer.)

Automatically inserting extra ways? Could work. Would be good to decide once
and for all how to map these things rather than letting the current
ambiguity reign.

Not that "deciding" means we have to immediately go out and fix every
roundabout, but a clear "preferred" and "deprecated" demarcation is usually
good.
