You mean, mention it somewhere? Sure (although it would be nice if the
documentation generator would automatically extract it from the source,
just as it extracts the Python version number).

Of course, such mentioning should explain that this is specific to
CPython, and not an aspect of Python-the-language.

What specific reference are you referring to?

It's clearly not affected.

It's covered by "As the standard library is not directly tied to the
language definition it is not covered by this moratorium."

>  Should this upgrade be backported to 2.7?

No, it's a new feature.

It should specify what this actually does in Unicode terminology
(probably in addition to a layman's rephrase of that)

Implementations are free to use any version of the UCD.
