In old, totally duck-typed, Python this didn't really matter, but nowadays

There may be case for leaving deg(0) undefined both for polynomials and
Laurent polynomials (and power series and Laurent series): it's at best a
shorthand (pace Nils' comment about dimensions) and needs to be handled
separately in code. So calling deg(0) could raise a ValueError or
-1
For the most part, because this proposed policy cannot be reflected in the
GitHub user interface:
The list of selectable labels in the drop down menu cannot depend on
whether it's an Issue or a PR.

I recently reviewed cases in the sympy polys code that handle the
degree of a zero polynomial:
https://github.com/sympy/sympy/pull/25784
My conclusion is that it is sometimes useful that deg(0) < deg(p) for
p != 0 but otherwise it is not really possible to use the value of
deg(0) for anything
Ok, I will do the same.

There seem to be two things we could do here:
1. Have some form of vote / discussion on whether the degree of the zero
polynomial should *ever* be -1
2. Modify the degree calls for the LaurentSeries and LaurentPolynomialRing
