Not in grid deployments, no, that is far from true.

So at least now I think I understand where some of your comments are
coming from.  Comments such as: why couldn't a server bind a key to an
assertion where the key was obtained previously, out of band?  I made
some assumptions about this use case and suggested a patch to the
profile to accommodate it (i.e., a timestamp), but at least one person
(Conor) had a problem with that scenario.  So I'm not sure what to do
about it.

Well, then I think the onus is on you to clarify these other use cases
so that we can take them into consideration.  The dialogue thus far
suggests this might be a useful exercise.
