I agree, but that's a UI problem, rather than a data model issue.  
Editor software should ideally have an 'reapply last set of  
keys/values' control, so you could instantly create another way with  
the same set of attributes as the last one.

Hm, yes. I was wondering about these when doing the Worcester ring  
road. My personal conclusion was that if we don't do them for islands  
in the middle of the road at (say) a pedestrian crossing, we shouldn't  
do them for roundabouts, either.

Option 3. You decide to do everything through individual ways, and  
smile sweetly at Imi (and other editor authors) asking him to include  
a "reapply same tags" feature.
