I share this concern.  It must be crystal clear that 'zh' does NOT mean Mandarin,
but rather any kind of Chinese.  Of course, there are cases where one might
deliberately be imprecise in tagging, but we should not be so sloppy in our
own definitions to equate the label for the superset with the subset, just as
we must avoid falsely limiting 'de' to "Standard German" or 'ar' to "Standard
Arabic".  (I recognize that this concern is largely independent of the
syntactic decision to use or not use extlang.)

We need to recognize that there are cases where having
an extlang might make sense, but none is available, so
the extlang approach doesn't help.  Some examples:
  - spoken Serbian and Croatian
  - Romanian and Moldovan.
