Not exactly. The actual relationship is MAY. The Prefix specifically indicates "(a language range) whose subtags are appropriate to use with this subtag" (Section 3.1)

MAY is a much weaker recommendation than SHOULD, in RFC 2119 keywordese.

That is true.

In any case, I now support having just the "zh-Latn" prefix.
