Doesn't happen.  The airplane manufacturer has to demonstrate evacuation of
the maximum number of passengers to be certified for the type.  The
manufacturer holds the type certificate, not the airline/owner.

>(2) more pax than have been demonstrated

Can't certify more than has been demonstrated.

Airline can do as it pleases as long as exits are not blocked and the aisles
are not reduced beyond a certain width.

The region that covers the type certificate holder (eg the manufacturer).
