In general, we try not to introduce changes that have a high probability
of breaking existing code, especially when what is being "fixed" is a
minor issue which almost nobody complains about.

This is even truer for stable branches, and Python 2 is very much a
stable branch now (no more feature releases after 2.7).

Perhaps, but it is not Python's fault if the IETF and the Unicode
consortium have disagreed on what UTF-8 should be. I'm not sure what
people called "UTF-8" when support for it was first introduced in
Python, but you can't blame us for maintaining a consistent behaviour
across releases.
