That's been deployed for a while, eg:
<link rel="canonical" href="/wiki/Foobar" />
at
http://en.wikipedia.org/wiki/Foo
I haven't found such code in MediaWiki 54916 snapshot from SVN
(currently seems to be running at WMF). I am missing the code (I've
looked into monobook and grepped for "canonical" through the subtree),
or does it use some kind of extension? The most logical place for it is
the monobook skin source code.
