I hope that, before the doctype is changed to html5, a substantial grace period is given for people to change to an HTML5 parser in their javascript code.
We will continue with well-formed XML output for the foreseeable future for exactly this reason. We don't need to stop emitting well-formed XML to use HTML5. I have tested trunk defaults ($wgHtml5 = true; $wgWellFormedXml = true;) with the Python SAX parser and it parses pages correctly, so no tools should be broken.
