Right. Because of that we can't just generalize the PROFILE_GET argument
list to include this. I'm thinking a PROFILE_GET_CONF that has a single string
arg before "groups", consisting of a comma-separated list of key=value pairs,
each overriding the global client parameter of the same name.
PROFILE_GET_CONF has the whole implementation, essentially same as current
but with each of your new parameters possibly coming from the override string
instead of from the global config. PROFILE_GET becomes a stub, invoking
PROFILE_GET_CONF with an empty override string.
