No, because then things would have been unstable before, no?

I actually think that we should remove most or all of the
cascade-drop-hiding hacks that are in the regression tests now,
not only that one.  They should not be necessary any more, and
they might be hiding things we need to know about, now or in
the future.  But I haven't got round to it.
