I doubt you can reduce it without causing problems for the system,
because some commands use more than one "command" internally.  Exactly
what are you planning to do with it?

It would actually be trivial to put a lower limit (see the
CommandCounterIncrement function -- you'll have to recompile), but I
guess I don't see the point.

There is no setting.  This is not configurable.
