I see no useful different between x.y and x.y.z here. All I want is if
someone installs one of our packages that package will work as expected.
If a package will only work with a certain revisions of a dependent
package it has to state say.

If we do not do that we are making it very hard for people to use Zope
packages: we are effectively telling them that we make no guarantee
about package stability and they will have to either use one of our many
KGS or figure out all dependencies by hand. I do not think that is an
acceptable message, and it certainly will not encourage people to use
Zope packages.
