It would be helpful if you could say what changes you have made, rather
than relying on reviewers to somehow figure this out for themselves. I
take it you did not use my suggestion, but I can live with the result.

I don't think it matters what vendors have indicated they would like.
If there are technical reasons that necessitate citing unregistered
media types in the draft, I would like to hear them. At the moment I
cannot agree with keeping unregistered types in the draft. I could
agree with not treating certain XML media types as XML media type,
but this surprising fact needs to be noted in the document.

Then I must have misread the document. Could you elaborate on how to
arrive at your conclusion, so I can make a suggestion for changes that
would prevent my misunderstanding? To give a better example, why is an
implementation prohibited to execute open() step #10 before step #1,
or where does the draft says it is allowed to do that?

A NOT_SUPPORTED_ERR DOMException would certainly be appropriate.
