-1 on the proposal.

The use of 'x-' introduces private use subtags, which are defined at length. If someone wishes to create a private agreement to use these for some kind of extension, it is none of our business.

The restriction to lengths of up to eight characters is for compatibility purposes, a restriction I agree with.

Punycode of up to eight characters in length (i.e. not very useful) in a private use tag is not our concern. Non-ASCII values break long standing compatibility, especially since a well-known use of language tags is in MIME headers, which are explicitly ASCII-only.

Language tags are identifiers, not the thing itself.
