I strongly disagree. Python 2 had no bytes type to get rid of. It had a string type that could not handle code points above U+00FF at all, and could not handle code points above U+007F very well. In addition, Python 2 had a Unicode type, and the types would get automatically converted to each other and/or encoded/decoded, often incorrectly, and sometimes throwing runtime exceptions.

Python 3 introduced the bytes type that you like so much. It sounds like you would enjoy a Python 4 with only a bytes type and no string type, and presumably with a strong convention to only use UTF-8 or with required encoding arguments everywhere.

In both Python 2 and Python 3, you still have to learn how to handle grapheme clusters carefully.
