Who's saying there's anything wrong with that? Not I.

My question is, what's wrong with the first part such that Devin
recommends against it?

> Also, keep in mind, these recommendations are not infallible.

Yes, Devin clears up in a later message that the official guide provides
no advice for the case where an API needs ‘bytes’ in Python 2 but
Unicode in Python 3.

> Be flexible.  Do what works.

Good advice, but nothing different from what I'm already trying to do.
