Just a theoretical thought, if we take -pinyin with prefix
zh-Latn- now there's no way to get rid of the prefix later.

So if folks later want "pinyin" with prefix cmn-Latn- and
others, but without zh-Latn-, they'd be forced to invent
a new variant, say -pinyin2, and that would allow them to
deprecate -pinyin in favour of -pinyin2.

If that is exactly what you want (later, when cmn exists),
you could use -pinyin1 now, and deprecate it in favour of
the later "real" -pinyin with the "real" prefix cmn-Latn-
instead of the slightly "unreal" zh-Latn-pinyin1 possible
today.
