You gave one example, which I'll address later in the mail, but more
examples makes your case more salient.

This is one I'm not sure I get, so let's discuss it.
Let's use a real world example (other than the one you use later):
Are you saying it reduces the ambiguity between K Street NW and K
Street SE (in Washington, DC)?
If this would be your example (and I don't know if it is) then I don't
see how it reduces ambiguity, since the name of the street will be
different.

What kind of local characteristics?

How does it give them more flexibility to tag what they see? Are you
suggesting that this replace (rather than supplement) the "name" tag?

You keep using the word "ambiguity" but the names appear to be unique
to me- strange, but unique.

How does it facilitate import of address data?
And please address the issues #2- users actually using this format.
That's the key feature- will human beings do it?
