No, since the acquisition context is only created when the object is
insert into the hierarchy somewhere (sloppy terminology here, I know).
And that can only happen after the instance has been fully created.

As an example:

   obj = Object()
   # obj has no acquisition context
   folder.obj = obj
   # folder.obj will have an acquisition context

In other words: in __init__ and everything you call from __init__ the
instance will not have an aq context. The context does not magically
appear.
