That was my understanding, too. I thought this would just mean
aq_base'ing the utility and aq-wrapping it back into the context (the
portal root). Without this, we start requiring users of the interface to
know when aq wrapping is needed and do it explicitly with __of__() which
I think we agreed was unacceptably detailed and ugly. :)
Alright, I've gone ahead and put code in place for this (albeit a bit
naively) with r72810. The next question is whether we should be doing
the same with adapters and subscribers as well (even though this
doesn't affect the whole tools-getting-acquired-properly issue).
One more thing: This acquisition wrapping should clearly be marked (with
comments) as something that's done to for BBB because some tools happen
to want acquisition. I think in the future, it should be discouraged to
expect acquisition in CMF tools.
To get to the portal root / CMF site, I suggest a pattern that is
sometimes used in Zope3: We register the CMF site object as a utility
providing ICMFSite (or whatever). Then whichever code that's executed
below the portal (and that includes CMF tools) can do
getUtility(ICMFSite) to get to the site.
Adapters and subscription adapters should not be acquisition wrapped.
