[Zope] restrictedTraverse without acquisition

[Jonathan Hobbs]

I have never heard or read anything about turning acquisition 'off', and I
would guess that it would not be a simple thing to do as many of the base
classes used within zope inherit from or otherwise use acquisition classes
(ie. acquisition is fundamental to many of the zope functions).
