I agree this is desirable goal.

I think the premises is that if you serve your content as text/html,
you're not expected to have it designed to work seamlessly with XML
tools. 

For the people interested in having their languages annotations properly
read by XML tools, the best practice would still be to have both lang
and xml:lang; for those only interested in getting their pages properly
parsed by browsers, the lang attribute should suffice.

But that seems like something that wouldn't have effects before years,
at the very earliest; not mentioning that this would also need to be
outreached to assistive technology vendors, etc.

In the meantime, we're going to leave out in the cold Web authors that
will need to choose between being valid (using their XHTML format of
choice), or provide effective language annotations.
