The spec is currently in the WebApps:

http://www.w3.org/2008/webapps/wiki/PubStatus

My assumption is that unless someone objects to it being there (rather
than HTML), it will stay.

Microsoft co-edited the spec, and made a public statement of support here:

http://lists.w3.org/Archives/Public/public-webapps/2012OctDec/0336.html

Mozilla indicated they are looking at implementing here:

https://www.w3.org/Bugs/Public/show_bug.cgi?id=17930#c3

There is an test suite included in this bug which adds to the existing
html5lib test suite, which can later be merged back to w3c.
