This could be a problem. Say that HTML 5 didn't have a combobox type,
but HTML 6 did. Refusing to render it at all wouldn't be a great idea.

... of course, if we had versioning then a more liberal mode could be
adopted for version numbers in the future. (hmm, this document is
written in an unsupported version of HTML, attempting to render anyway, IE9
supports this version [upgrade now]).

The other issue is that mistakes DO happen. OTOH, QA tools do exist
and adopting a publishing process that involves the use is a QA tool
isn't all that difficult.

One argument that I haven't seen mentioned is QA testing. How is a QA
tool supposed to test a document for conformance to a specification if
the document doesn't indicate what specification it is written against?
