I'm not a mathematician, but believe 0^0 is undefined. Sagemath being
consistent with something that is wrong seems to be a bug to me. Just
because X does it wrong, I don't see why there's a good reason to follow X.
Submitting that as a bug to Python and MPFR developers seems sensible.
Following them does not.
FWIW, in Mathematica.
