In my experience it would be useful to keep the bytes warning for
implicit representation of bytes in string formatting. It's still a
common source of issues in code.
I am with Christian here. Still notice a possibility of people running into this because all the Python2 code is not dead yet.
Perhaps this warning might stay for a long time.

BytesWarning has maintenance costs. It is not huge, but significant.
Should we know by how much so that the proposal of `-b` switch can be weighted against?
