Sure it's possible, but I'm arguing about whether it's worth the
effort.  There can be loops like a -> b -> c -> d -> e -> a.  Given
that nobody has even bothered to get git to print an error message
when a builtin command is overridden, do you think anyone will be
interested in this?

Yeah, I agree with this to a large extent.  It's nice to have a
minimal set of unambiguous commands for the purposes of communicating,
and I'm quite happy with the present state of things.
