I don't have time to read the list normally. :(

Of course. Zope already doesn this for security.  It does this
by brute force most of the time, although there's now more API
support for it. There's a 'containment' keyword flag argument
to the aq_acquire method, so, at least from Python, you can
force acquisition to search *only* the containment hierarchy.

I think that there's merit to providing more control over how
acquisition happens. This is consistent with making acquisition
more explicit.
