This is totally unnecessary. And then the above seems contradictory with the first sentence. Sorry to be dense but I really don't follow what you're suggesting. If you're okay with single dmmap AS, how can you not be okay with the quirks of dealing with global AS? The only exit from that problem is having multiple ASes.
