Right, exactly. And in any code that does not and cannot run on Python
2, the warning about bytes and text comparing unequal is nothing more
than a false positive. It's like having a warning saying "In previous
versions of Python, this arithmetic operation might have overflowed".
In ALL current versions of Python, that is irrelevant noise. Turning
on the warning is therefore not a good thing; the non-thinking policy
of "turn on all warnings" is not the best default.

If a warning is ALWAYS a false positive, it is better to silence it
than to have noise that makes *other* warnings less visible.
