They might not be that useful at all :)

That said, I went off & entered a 1/2 built roundabout this week - it's 
almost done, & will be the 'mount point' for a huge amount of building 
work soon.  I figured it won't get anyone lost if they find a 2-exit 
roundabout that almost exists :)

I quite like the highway=construction:xxx idea, but perhaps using it 
implies a commitment for monitoring it?
Sort of like FIXME tags..
It might also be useful for routing software, along the lines of 'best 
avoided' at the junctions.
