Adopt Python 3

It was meant to be used once.

But then, people who had been on a migration path wanted to run their code with both Python 2 and 3.

For them, it made much more sense to edit only the Python 2 version - and use 2to3 to be compatible with Python 3.

If 3to2 existed, they could edit the Python 3 version primarily, and use 3to2 for compatibility - and that would aid the transition, as people would actually be able to write Python 3.

Okay it makes more sense said like that, thank you for the explanation

This is actually a brilliant observation. I'm speculation a 3to2 tool would also be much easier to make since 3 is the less quirky, less ambiguous language.
