[Zope] aq_explicit

What is the status of aq_explict and Zope 2.0.1 ?

aq_explicit does not prevent acquisition with all objects I've
tried. With the above example, if 'foo' is not in the current
folder, yet is in the parent folder, the example still succeeds.
I.e. there is no difference in behavior with or without aq_explicit.

Same holds true for <dtml-with aq_explicit>

Am I misinterpreting the purpose of aq_explicit?
