I'm not "arguing for" what I perceive to be an inferior solution, though
I am "arguing against" those solutions that are even worse, such as 10D
home and foreign area code dialing.

I suppose you'd construe that as a "yes", but that oversimplifies my
position.

That's odd, since that's what the same telcos have advocated in other
areas that have faced the same things.  Perhaps they got shot down by
the PUC when they proposed it in private, so you didn't hear about it.

0+7D was eliminated NANP-wide at the same time as 1+7D, when the first
NNX area codes were introduced.  The problems are the same.

I hadn't heard that operators had been eliminated, though last I checked
the charge for talking to one was several dollars unless one of the
PUC-mandated exceptions applied.

The INC UDP does not acknowledge any costs, either to the industry or to
customers.  Nor does it claim any benefits, just manifest necessity.

Other INC recommendations, such as how to handle numbering plan
expansion, are also presented as manifest necessity--and rely on the UDP
being adopted.

It's a drop in the bucket in comparison to the external costs, and it
could be argued that the ongoing costs of maintaining a non-uniform dial
plan are worse.
