Sorry for the late comment on this, but having thought about this a bit,
I agree that this should not be mandatory.  If a caller realizes after
starting the call that it is not an emergency (the person choking has
their airway clear; the parent realizes a child has dialed 911, whatever),
they should be able to terminate the call.

Though I am no expert in this, it's my understanding that this is
not behavior supported by the current cellular networks, so I
believe that it would be both simpler and more appropriate to
define user terminated calls as permitted behavior.
