Well "bad" from the point of view of "doesn't scale on the Internet",
yes.

You're right though, you shouldn't be surprised, because I've been
saying the same thing for over two years!  Web services, as most
people know them, are a mistake, based on a misconception of what the
Web is, and how it works.

I was trying to be clear that I was talking about late binding.  I agree
that WSDL supports loose coupling of interface and implementation.

I don't think we need to have that argument, because I don't expect that
anybody in the WG would assert that the common use of WSDL (as an IDL)
supports late binding.
