Not just fundeps; the originally cited behavior of equality constraints
could also stand to be documented. In fact, I'd noticed a few shortcomings
in equality constraint documentation --- including the question of, are
they always enabled, or are there particular extensions that enable them?
And if so, should they also have their own extension that becomes implied
by those other extensions? So it's not even just documentation.
