Where is it defined that user agents must ignore the 'x-*' part? I don't think
that anyone can infer what 'en-us-x-hixie' means. There is no semantic
difference between 'en-us-x-hixie' and 'en-us-x-myscript' or
'en-us-x-my-invented-orthogra-phy'. It would perhaps be smart of user agents to
- by default - ignore the '-x-whatever' part. But I don't think it is said
anywhere that they should.

First one needs to know what the proper treatment of such tags is. From BCP47:

]]
2.2.  Language Subtag Sources and Interpretation

   …

o  The single-letter subtag 'x' introduces a sequence of private use
      subtags.  The interpretation of any private use subtag is defined
   …
      solely by private agreement and is not defined by the rules in
      this section or in any standard or registry defined in this
      document.
