Actually, I believe the default /usr/bin/python symlink makes sense to
have, in order to be used for python scripts that don't care which python
they use.

Let us assume someone has only python3 or python2, does it make sense to
prevent people from using polyglot code simply because an arbitrary
decision was made to assume one or the other is the official python version
to run the code under?
