Well, my suggestion would that we _should_ make it work, by having the %s
format specifyer on bytes objects mean: str(arg).encode('ascii', 'strict')
It would be an explicit encoding operator with a known, fixed, and well
specified encoder.
This would cover most of the use cases seen in this threadnought. Others could
be handled with explicit str formatting and encoding.
Imho, this is not equivalent to re-introducing automatic type conversion
between binary/unicode, it is adding a specific convenience function for
explicitly asking for ASCII encoding.

Certainly doesn't work on Python 3 right now, and never should :)
