In XML empty attributes are not allowed, so the value has to be something (even if just en empty string). In place of using true/false the standard says that is must be either the same as the attribute name or an empty string (for XHTML5). This is what we are stuck with for XML serialization of HTML5. I think a framework should rate compatibility over conciseness. And adding a value to a boolean attribute I think is a very minor hassle.

I will say that this time is the best time ever to serve pages with application/xhtml+xml, because all browsers supports it. IE was the road blocker for year, but since IE9 it supports it as well. The points about infrastructure and optimization are so vague I can hardly guess what the writer thought about. Se a list of the default value of the Accept header for various browsers from Mozilla: https://developer.mozilla.org/en-US/docs/Web/HTTP/Content_negotiation/List_of_default_Accept_values All except IE8 supports application/xhtml+xml.
