That's true in some sense, but doesn't much matter. Just like we have to 
assume that an operator includes a valid geo address, we have to assume 
that the civic address is a complete and preferably validated address, 
at least to the street level.

(Obviously, in either geo or civic case, things like building names or 
floor numbers may not be included.)

The notion that geo is always sufficient for routing is mistaken. If 
your geo resolution is such that it includes the whole North American 
continent, it is not particularly useful for routing. This is exactly 
the same problem as if somebody were to only include the country and 
state, say.
