Indeed, and as you discovered, it is in fact still defined. Even <xmp>, 
<listing>, and <plaintext> are still defined in HTML5. (The latter three 
only have their parsing defined so far, but rendering rules will be 
forthcoming in the rendering section.)

However, that doesn't mean they should still be conforming in new 
documents. The point of conformance is to provide a way to perform quality 
assurance on documents to verify that they are the best they could be 
according to the current state of the art. Leaving <font>, bgcolor="", 
align="" and so forth as conforming features does authors a disservice.
