I can easily imagine it's reasonable to use them for campings in some corner
cases where a single area doesn't work.
multipolygons can solve any disjoint area problems, you only need a site
relation if some members are nodes or linear ways or relations.
Only when the outer members don't touch, for instance two buildings that
share a wall, but are of different heights. Yes you could map each
building as a multipoyglon .. and then map the non over lapping building
ways to the university multipolygon .. but loose the name and ref number
of the buildings..
A site relation is better as it is simpler and better matches the data.
