Thanks for the examples and conclusion given.  This is a strong reason to
demand its usage in wiki docs and IMO we should even suggest their usage
generally, regardless of the construction site's complexity.

Even when neither multi-layered nor nested buildings exist, they may aid
in data validation and plausibility checks. Yet they may ease maintenance
work for oneself and other mappers, since they usually convey an overview
of all the parts present. But of course it depends on mapping workflow if
this is true to a particular mapper.

Lastly, we should keep in mind that any construction site may change in
time. This may be one of the weaker arguments, but still adds IMO to a
general recommendation of their usage.
