In a small side note: I still don't know how we recommend using

and
have "3.4.0" as their version number.
I don't think we've defined what "the egg-version of Zope 3.4.0"
means
(nor do I think we need to as part of a classic zpkg-based Zope
3.4.0).
The 'and have "3.4.0" as their version number' I consider a non-goal.
Maybe a meta-egg that would introduce the dependency of
"zope.xx==3.4.0"
as their dependency would allow that to happen because if this gets
involved in a working set then the synchronized satellites would be
restricted to the exact version.
Are you suggesting the satellites would have this dependency? If so,
-1. If not, and this is just used as a way of collecting the eggs, I
think this isn't valuable, and hence is a decoy.
I might have stated my goals the wrong way. I find it valuable to be
able to predict which exact versions of things "get pulled in" from a
buildout.
The current way that dependencies are declared is that when I run
buildout in a year I'll get the zope.app.publication-3.5dev-r122 egg
on a stable application. I don't want that. I want to again and again
and again get the 3.4 egg of zope.app.publication because those eggs
where tested together.
OTOH. I'm just remembering that Jim talked about some `freeze` feature
for buildout ... is that what I seem to want to tackle this issue? ;)
Maybe:
