[please don't top-post on technical lists]

Extending an existing command may be reasonable, if the amount of
information being added is compact (if you are adding several kilobytes
of information, that might justify a new command, if only so that old
callers don't waste time receiving large amounts of data on the wire
just to sift through and discard it all to get at the older content they
cared about).
