It has not only been considered, it's been planned.  It appears in the
Bellcore "Notes on the Intra-LATA Networks".

The plan is that all intra-NPA calls will be dialed with seven digits,
whether or not a toll charge applies.  Moreover, all inter-NPA calls
will be dialed as 1 + 10 digits.  Non-conforming areas are expected to
implement these procedures during the 1990's.

It would seem that the 215 area code has just announced such an
implementation.  In NJ, we've had this in effect for several years.
When it has become universal, then there need be no distinction
between area codes and 'office' prefix codes.  That will allow many
existing NPA's to be further sub-divided without exhausting the supply
of possible area codes.

Note that this numbering plan has worldwide consequences: Any country
which permits customer-dialed calls to the US or Canada must implement
changes in its dialed-number validation translations before we can
move forward with this.
