But, speaking of en-banc dialing on cell phones, do you find that
users typically enter the 1? I certainly don't. 10-digit is the most
common form I see.
We don't support 7 digit (we killed it at the same time Ma Bell did in
our area).

The problem is, right now, you are right. If someone dials 9 then 8,
they get fast busy immediately (because there should have been a 1).
But after the change you mention, if they are trying to dial the very
common toll-free NPA 888 and forget the 1, they will instantly be
talking to the suicide hotline.
