Yes, I am in agreement. Boris also raised a number of excellent points as

Sometimes I wish I could be more closed minded to the possibility of being
wrong. :)

It looks like even dropping DOCTYPE would cause problems, since it would
then trigger "quirks mode" and cause HTML 5 to be rendered in a really poor

... unless we drop DOCTYPE, but have a <meta> which declares to document to
be HTML 5, so the logic was "If no DOCTYPE, then use 'quirks mode' unless
<meta HTML-version=5>"...

... which would be really clumsy and error prone.

On the other hand, "ignore DOCTYPE unless it is wrong, and then activate
'quirks mode'" is very clumsy and error prone as well.
