-1. .name() is documented (and users familiar with it expect it) as
returning the name of the character from the UCD.

It doesn't really matter much to me if it's non-sensical - it's just
a label. Notice that many characters have names like "CJK UNIFIED
IDEOGRAPH-4E20", which isn't very descriptive, either. What does matter
is that the name returned matches the same name in many other places
in the net, which (rightfully) all use the UCD name (they might provide
the alias as well if they are aware of aliases, but often don't).

Python doesn't use regexes in the language parser, but does do \N
escapes in the parser. So there is no way this transformation could
possibly be made - except when you are talking about escapes in regexes,
and not escapes in Unicode strings.

If there would be a reasonably official source for these names, and one
that guarantees that there is no collision with UCD names, I could
accept doing so for Python as well.

-1. Readability counts, writability not so much (I know this is
different for Perl :-). If there is too much aliasing, people will
wonder what these codes actually mean.
