Well, it's definitely a good thing (TM), and it already works quite
satisfactory with Emacs/Gnus/mule-ucs (except some characters present
in UCS are not supported by Emacs' internal encoding).

Those features are not really that important (besides perhaps
auto-detecting the charset of 8-bit chars in headers).

However, there is a bug somewhere in core Emacs which makes it
misbehave when i receive messages with 8-bit content-transfer-encoding
and characters in the range 0x80--0x9f (which often happens when i
receive messages in UTF-8). I store mails in nnmbox backend, and when
i receive such a message, i get ENORMOUS time delays when pressing `g'
in a group buffer, and article numbering gets broken (displayed number
of articles in a group is overestimated), and such things. I think
this is because Emacs uses "intelligent" auto-detection algorithm
which wants to interpret a `mbox' buffer as if it were in some charset
(mbox is opened in raw mode, but this does not help to switch of this
"intelligent" behavior, and certain character combinations choke
Emacs). This is a long-standing bug which is there for more than a
year, but i don't know how to report it... :-(
