I don't think there's any connection between the way 2.x confused text
strings and binary data (which certainly needed addressing) with the way
that 3.x returns a different type for byte_str[i] than it does for
byte_str[i:i+1]. I think it's the latter that's confusing to people.
There's no particular requirement for different types that's needed to
fix the byte/str problem.

And of course it's too late to make any change to this.
