That makes sense, and is what I had actually thought/hoped was the case
(although I didn't know the details about plug format and hole pattern).
So when they say a 15 amp circuit can have no more than a 15 amp
receptacle, it just means that you can't put in a plug that could accept
a 20 amp appliance.  Admirable.  If all "15 amp" receptacles can
actually pass 20 amps without melting down, even better, although that
picture I found on the web suggested that this is not strictly true.
