Could you please provide an explicit example when we would want to do
'something different'?

The only place where it's going to be used is in the network drivers
and only when the original mbuf chain is not usable.  You don't
want to coalesce mbufs otherwise/elsewhere.  The old chain is freed
in case of error on all places where this routine is going to be
used.
