I can see how appendix C would lead to your views, it was pretty much a
disgrace really, as without changing html specification in any way, it
suggested that it was OK to serve xhtml (necessarily syntactically
incorrect HTML4) as text/html. Thus it was relying on the fact that
browsers didn't implement html4 as specified, which was a pretty strange
thing for the organisation standardising html to do.

But that's in the past and the polyglot document isn't doing that at
all. It is documenting the way one may use xml tools to generate
documents that _by definition_ work as intended when served as text/html 
and parsed as html5.

Actually of course it doesn't tell users how to generate documents that
meet these constraints, just documents what the constraints are, which
is a problem that needs to be addressed at some point, but still it's a
necessary and useful start. Also the actual constraints needed are more
arcane than they could be (because making them less arcane wasn't a
design consideration in html5 as currently specified).
