Kapil's also right when he says that utilities by principle are context-less components.
By principle all Zope 3 code might depend on setSite to work as expected. We just don't pass that 'site context' explicitly to the component as in Zope 2.

contextual lookup is very a different notion, that context implementation dependence. utilities don't have context implementation dependencies in zope3, the majority of cmf tools do.
Just so we are clear, can anyone point to a good example of a not-trivial-to-change place where CMF tools have inherent dependencies on acquisition?

Security is inherently "placeful" in Zope2:  it requires being able to
verify that the logged-in user is authenticated in a user folder which
is in the "scope" of the protected resource.

As far as I'm concerned, Zope3's model is *not* intrinsically superior:
 it doesn't support the use cases of the Zope2 model at all.  Let's just
forget the "Zoep3 is better" mantra and find a workable near-term
solution here:  if we have to re-implement / tweak some Zope3 machinery
to make it "play nice" in Zope2, then let us do so, rather than
distorting both in a misguided effort at "Zope3 purity."
 - If that means continuing to use 'getToolByName' for traditional tools
  which need Zope2 security, fine;  folks who implement new utilities
  which don't need that compatibility can register them as pure

 - If it's easier to hack the LSM stuff to automagically wrap those
   returned  utilities which implement IAcquisitionWhatever, fine;  if
   that means in turn that folks must use the Zope2 LSM version in
   subsites, fine.

I guess the main worry is if we go down a route whereby we *always* need a zope 2 version and a zope 3 version of some piece of code. Of course, this is often the case anyway, but that doesn't mean we have to make the situation worse. KSS, for example, had a set of components that worked well across both zopes, and now needs conditional imports for its base classes.

This is not "rape" by any stretch of the imagination;  this is
"adaptation" at its best.  Let's be pragmatic here, please.

The Hungarians have a colourful idea of language. :)
