I would say it could be a bad idea. For any protein string there are
multiple possible back translations, and this cannot be captured
fully as a nucleotide string even using the IUPAC ambiguity chars.

We debated this back and forth for Biopython, and decided to leave it
out. It wasn't possible for a simple back translate to a simple string to
handle the use cases we considered, and other options like returning
a regular expression covering all possible back translations were too
complex (for a core sequence method/function).
