I don't think anybody is advising anybody to use XHTML2.
Html5 includes XHTML5 as an integral part. There's no reason not to use what's available.
And if you use polyglot (x)html5 it also just works.
It's also clear that there are many out there who do not see the advantages of well-structured valid code, of having a readily available and complete toolset to parse, change, transform, automate and manipulate xml data that can be used on your webpage source just as well, ...
But not understanding or seeing the advantage for yourself gives you no right to dismiss it on somebody else's behalf. I'm sorry, but it's just not right to do that.
