How would you know that the powerful and unfathomable Designer hadn't stopped them from appearing when they would otherwise have evolved?

LOL! One could certainly claim such. But you'd be the one who'd have to make and verify the claim. After all, a negative result would be worse for the hypothesis that flagella evolved, than it would be for Behe's hypothesis.

Why would I have to verify the claim? By its very nature it is unverifiable. That is the nature of the problem that ID would introduce into science. To take the opposite case, if the flagellum did appear to evolve how could you discount the proposition that the Designer dunnit? You cannot, because ID is not science. By the very nature of its claims it is unfalsifiable.
