I take that back. If you start from

and you are interested in peeking the history a bit deeper, you
should be able to ask "I have a shallow history that cuts off at
these commits. I want my history deepened by N commits. I do not
care where your current tips are, by the way." with
git fetch --deepen=3
and end up with
> (you)
> o---o---o---A---B
without getting the new history leading to the updated tip at the
upstream. If you want the new history leading to the updated tip,
you can just say:
git fetch
without any --depth nor --deepen option to end up with:
> (you)
> A---B---C---D---E---F---...---W---X---Y---Z
instead.
