The real problem is that there's no way to show the former state of a 
relation, and I tend to fix errors whenever I find them. I know I've 
recently fixed US 10 in the Minneapolis-St. Paul area, mostly where it 
overlaps with Interstates. If you're better than me at figuring out the 
history, see: http://www.openstreetmap.org/browse/changeset/5247114


The most common problem I see is when someone splits a way to create a 
bridge, and for whatever reason the newly-created ways aren't part of 
the relation.
