We tend to explicitly tag whether something belongs to the site or not. 
You might, for example, have a bridge spanning the site or other kinds 
of "transit routes" that are not part of the site, but serve to travel 
through/across the site without entering it. A rule like the one you 
suggested would make that impossible.

The relation would express whether something is logically part of the 
site; the geometry would express whether something covers the same 
ground as the site. This is not the same information.
