Well an XHTML parser (and serializer) is a lot simpler, which is a pretty meaningful problem to solve.
What problems does xhtml create?
The main one is that even a slightly broken XHTML document will fail to render. HTML is much more forgiving.

Perhaps, but a combined html and xhtml parser is more complex than just a html parser. Since html already is entrenched, xhtml would be in addition to html, not instead of.
