The number of things do not matter.  "user friendly" does not
matter.

They do not matter plumbing commands intended to be used in scripts.
What matters more is being predictable.

The silly example you saw in the discussion thread can be solved
even if by default we showed everything.  The UI can count the
checkboxes it is going to turn into command's arguments (i.e., "I
want to ask you about these pieces of information"), and if that is
empty, just can refrain from invoking the command.  But that is
arguably _more_ work on the script.  A simpler rule "we give only
what you ask, always, no exceptions that depends on the number of
things you ask (like when you ask for zero things)" would end up
being easier to use.

And it is more predictable.  If you ask for two things, you get two
things.  If you ask for one thing, you get one thing.  If you ask
for zero things?  You get none.

So...?
