But it's categorized with the "Small island developing States" class of
code elements.  As soon as we start trying to divine the UNSD's intent
here instead of reading their categories, the gates are wide open.

Mark articulated a good use case for 001 back when we first starting
talking about M.49.  "fr-001" explicitly means "French as used anywhere
in the world," that is, internationally acceptable French, as opposed to
simply "fr" which leaves it unspecified whether the French thus tagged
is acceptable in, say, Canada.

This is also the justification for the pending "classical Sanskrit"
variant; it makes the "classical" qualifier explicit instead of
implicit, in those (perhaps rare) cases where that is important.

By contrast, what does "language X as used in the CIS" tell anyone, for
any language X, in any geographical or other context, that either a more
specific tag like "xx-KZ" or a less specific tag like "xx" would not
already cover?  That is my second complaint against 172, the first being
that UNSD categorizes it as an economic grouping.
