I think the problem is specific to CROSS JOIN, because only for that is
there a temptation to make an analogy with comma.

We do have the binding-strength question addressed explicitly somewhere
else, I believe (probably on the SELECT reference page). I don't really
feel a need to duplicate that here. I think the footnote approach might
be the best solution.
