Agreed.

I'm somewhat dubious about the need for 1) as we do have a
mechanism, albeit a little tedious, to effect these kind of
dependancies. And in this case at least 2) shows us that
there is actually a slightly deeper problem that needs to
be addresses. I'd be surprised if we really end up needing
1).
