All well and good.

*UNTIL* you get assigned an NXX NPA that is _already_ in use as a prefix.
  773, 847, and 630  were _all_ in use as prefixes within the 312 area-code
  (and in the split-off 708 areacode as well) before those sequences were 
  "legal" as an area-code.

"Now What?" applies.  <wry grin>

Maybe in *your* territory.  :)

In 312/708/630/847/773/224, dialing patterns are 7D or 11D  ( 847/224 is
11D only)

Lots of places have *NOT* made that transition.  It is fairly _expensive_ for 
the telcos to implement.

"Speak for yourself, John" applies.  _Mandatory_ 10D dialing does *not* exist
(yet) in *many* areas

Mandatory 10D dialing does have non-trivial costs associated with it -- both 
to the telco, and to the customers thereof.

There _is_ a significant performance issue -- and directly related increased 
costs -- in supporting mixed 7D and 10D dialing.

To use 1+ for "toll alerting", in locales where intra-NPA can be toll, and
inter-NPA can be local, you have to incur one of those sets of increased
expenses. And the 'inconveniences' to the customer.

It is a trade-off as to which is 'worse' for the customer.  <wry grin>
Different utility commissions have decided that issue in different ways.

1-800-800, at least, has been in use for a number of years.
and I'm pretty sure I've seen  1-800-900 numbers.

You need a more cosmopolitian view --  This scheme has been in effect for
20 years, locally.  *NO* chance of getting it reversed.  In other major 
metro areas something very similar has been in effect for much longer.
Most big-city systems have charged on such a basis for a long time now.,
