> A HTML parser can become a XML parser by disabling a bunch of special-features

Even if this was true it would still increase complexity to have two parsing modes compared to just a html parser.

The idea would be to eventually deprecate "legacy" html, of course.

Whether that kind of backwards-incompatible breakage would ever become acceptable is a completely different story. But we ditched Flash, ActiveX, Silverlight, and Java applets, so who knows what could have been!
