So each feature that temporaly shown in HTML5 spec and got some more or
less experimental implementation will be forever minted in the parsing
algorithm? I see your point Henri, but there should be better approach
how to handle such situations. I understand that for legacy reasons we
need to handle plaintext, xmp, etc in the special way. But newly
proposed elements shouldn't create such legacy if possible.

Addition of hgroup was quite controversial from the start. And I don't
want to be hostage of browser vendors who at some time decided to
implement support for element without broad consensus. Of course early
implementations are important for getting feedback. But early
implementations should have impact on the HTML5 spec if feature turns
out to be useless.

What are the real practical consequences of instantiating element as
HTMLUnknownElement instead of HTMLElement? How can it break site? Are
there any sites which will get broken?
