Does that apply for coastlines as well? Or do coastlines not even need
the multipolygon?

Good to know. I wonder how we can make multipolygons more user
friendly? Maybe a magic "convert to multipolygon" tool, that starts
with one way (say the golf course in the previous example), converts
it to a multipolygon, and converts any other affected ways (the
landuse=industrial) as well.
