Yes - a while back I noticed one example of someone deleting all the 
inners from a multipolygon relation, so I've been on the lookout for 
relation-related errors since.  There are a few examples of iD users 
"creating relations for no purpose" but I've not counted those as 
"errors" because what results is not "wrong" - it's just using more data 
than is necessary to represent something.

However, the data that I'm looking at is primarily England.  There 
aren't the same underlying imported landuse multipolygons that you get 
in parts of the US or the NL, or the manually added wood/forest of 
Germany, so there's less to break in that area.  About the only large 
wood/forest area in the area that I look at is Cannock Chase, and that's 
just a way:

(the "note" on that correctly indicates that there's a more work to be 
do there** - separating the "Chase" area from what's actual woodland 
would be a start)

Cheers,

Andy
