There are far far more editing tools than there are browser implementations, using the xml syntax but parsing it differently inflicts costs on all those tools and the users of them. For the special case of mathml and svg the html5 parser works round its own problems with a "foreign content" hack, but for everything else, including ironically (x)html, the natural behaviour of content generators to use /> syntax for empty elements is defined to be broken in html5.
