wichert is right, the existing use cases — or say, at least
p.a.linkintegrity — have _not_ done without it.  in fact, the
confirmation view (i.e. "you really wanna delete this?") relies on the
(acquisition) context.  otherwise it could never be rendered as
something that looks like a "regular" page.

however, the monkey patch used here is only partly applied for zope
2.12, and the bit where the view gets aq-wrapped is not[*].  since it
remains to work, though, i suspect that wichert's problem could be
something else...
