AFAIR, there are some non-trivial aspects here, some of them political
and even ideological.  There's PRC and there's ROC (a.k.a. Taiwan),
and I'm not sure what will each group say about the proposed changes.

So unless we have a representative group of Chinese speakers from both
camps (traditional and simplified), and they agree on some change
without any controversies, I'd rather not touch this ticking bomb with
a 3-mile stick.  The current text might not be 100% accurate, but it
has been there for many years.  I'd rather not risk causing a
diplomatic incident by a change in Emacs.
