I do accept it, but it's wrong, so I want to fix it. If we can come
up with a set of rules that makes it unambiguous how to fix the
situation, we should fix the data, once and for all, not force
everyone using the data to fix it each time they use it.

It's a rough proposal :). Seems relatively easy. Find the larger
polygon, multipolygon relation, or boundary relation which intersects
with the area and has the same primary tag (e.g. landuse). If it is a
polygon, turn it into a multipolygon relation. Then add the inner way
to the relation as an exclave or inner way.
