I still fail to understand your problem here. Of course coverage and usage
won't match 100%, that's the reason why it should be tagged with 2 tags /
distinct objects where necessarily.
What kind of mess are you refering to? It will conceptionally be 1 land
layer (landcover) and one landuse layer (landuse), and probably even more
different layers like administration, maybe geographic regions (names,
these are there, but not well mappable because of blured boundaries, huge
spatial extension, ...), etc.

IMHO the problem why landuse polygons add so much complexity at the moment
is generalisation (huge generalized polygons, often multipolygons,
extension to the road center). If people wouldn't include roads and other
areas with differing landuse into big generalized polygons but would rather
map small overlookable areas atomically it would make things easier for
maintenance and for adding new stuff.
