[same text posted to a different note, but I'll repeat it in the
proper thread... In short I'm against the functionality change as I
don't see a reason for it. It doesn't buy you any more security; the
introduction of the ability does, but not the modification of the
default as long as it's documented.]

I actually think it should authorize all by default. That's what it's
done before and it's a behavior change. Had it been a bad thing, I'd
of course say otherwise. But I think the default user case will be to
authorize access to all contexts. The rouser, etc, cases are already
convenience wrappers likely to be used by people authorizing a user to
access to almost everything. Contexts also have not been a common way
to separate different security data areas.

The *ability* to limit to a context is certainly important, but I
don't think it needs to limit to just "" by default. Assuming that's
what's going on, because I'm speaking without having read the code of course.
