That's weird for a couple reasons.  One, that's not even the discussion
that I was thinking of.  I'll check in the morning to see if I can find
it.  Two, I was clearly full of it... I really don't see how I came that
conclusion.  I don't even see any other related extensions that I could
have been confusing either thing with.
