It's a bizarre situation.  Right now the registered RFC 3066 tag
for Mandarin is zh-guoyu.  When ISO 639-3 is incorporated in the RFC
3066 scheme, the standard tag will be zh-cmn, and zh-guoyu will be a
grandfathered equivalent -- permanently valid, but deprecated for new uses.
(This assumes that there are no changes in codes before 639-3 becomes final.)

If we act *now*, we can register zh-cmn (deprecating zh-guoyu) for
Mandarin generally, zh-cmn-Hant for Mandarin in traditional script,
and zh-cmn-Hans for Mandarin in simplified script.  Due to changes in
our process, however, we will temporarily lose this flexibility shortly.
So if you expect to need these classifications in the next year or so,
please file forms right away.

Likewise, zh-yue-Hant and zh-yue-Hans for Cantonese in traditional and
simplified script respectively can likewise be registered now,
assuming that Cantonese is ever written in simplified script.
The tag zh-yue will not be deprecated in future (on the same
assumption as above).

Currently not, but if you want them, get them while they're hot.

continent, a part of the main.  If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friends or of thine own were: any man's death diminishes me,
because I am involved in mankind, and therefore never send to know for
whom the bell tolls; it tolls for thee.  --John Donne
