There always have been two methods of doing this since multipolygons were 
invented: tagging the relation, or tagging the outer way. Tagging the relation 
is somewhat prettier indeed.

One always have to be aware of possible offsets in the imagery, but in Belgium 
I think it's all pretty good. I've actually never even encountered a place 
where one has to re-align the images (which doesn't mean there aren't any of 
course).

Long time ago I checked a few of the national geodetic points and see how they 
align with the imagery, and the result was "very good".
