Well, part of the problem here is that I've been talking with Ilias more
about what's intended here and the fwu-* stuff that Rob rejected is
indeed not right.  We should drop it and replace it with something that
really addresses the underlying problem (which is how do you know
how/where to find some GUIDs) and I think we think it's something that
can be shared between projects too and so be easier to convince Rob that
the next form of it is right (or the right direction).
