Both you and Eric U suggesting adding new tests for this in the
original thread on 8/9; in fact, this whole issue got a fair amount of
discussion then, and this round hasn't really added anything new.

I'm happy to wait a little longer if others want to come up with some
other suggestions; I apologize if my previous response sounded like I
was throwing down a gauntlet or otherwise not open to ideas; that was
definitely not my intent.

Rather, I was attempting to say that unless someone else has other
ideas, the right path forward seems fairly clear to me and that I
intended to proceed down it.

Does that seem more reasonable to you?
