I think it's fair to say that right now, <html lang> is not so
uniformly useful that authors need to be warned if they omit it.  If
the *average* page (some random hit from Google, say) doesn't have any
use for it, then I don't think it should raise a warning -- warnings
should be useful to most authors, not only a small minority.
Otherwise you're making warnings as a whole less useful.
