I would think that anyone actively trying to use pythontex3 would be
knowingly using python3 and hence having python3 installed. The
devscripts package is a good example of such a thing (lots of Suggests
and explanation in the package description and README).
Alternatively, if one wanted to be extra-careful, the
/usr/bin/pythontex3 script could, instead of a symlink, be the
following (untested):
#!/bin/sh
if which python3 >/dev/null 2>&1
then
exec /usr/share/texlive/texmf-dist/scripts/pythontex3.py "$@"
else
echo "You need to have python3 installed to be able to use" >&2
echo "the Python 3 version of pythontex!" >&2
echo "Exiting." >&2
fi
