Clearly "character set" is not used in the standard sense here, but
in a sense like "grapheme-to-phoneme mapping".  (Technically, "Latn"
is not a character set either, but a script that corresponds to a
character repertoire.)

Administrative convenience, basically.  For every relevant langauge
there is a Hanyu-Pinyin-type orthography; rather than devising individual
subtags for all of these, we devise one, which when applied to Chinese
signifies Hanyu Pinyin.

Take two turkeys, one goose, four               John Cowan
cabbages, but no duck, and mix them   
together. After one taste, you'll duck          cowan at
soup the rest of your life.
