The problem with this is that if we ever want to add the range argument to
LISTGROUP later on (since it's looking like specifying this may involve
more details than we want to deal with at this stage), you end up with a
very ugly way of specifying that in capabilities.

It also then looks odd.  We would be leaving LISTGROUP as the only command
capability that isn't its own line in CAPABILITIES.  (That's more of an
aesthetic argument, though, and isn't as strong.)
