If neighbouring fields are farmland and meadow you need to split them.
And as we all think about mapping roads as areas e.g. landuse=highway
landuses have most likely to stop at roadsides.

I consider layer=* on landuse as beeing broken. If you need to cut out
a part of an landuse thats what a multipolygon is for. For me
landuses may not overlap.
