There won't be such correspondence. AFAIK, all 4 packages I mentioned
above maintain backward compatible codebases, so it's not like they
depend on the latest Emacs.

And if some do, package.el allows to specify the minimal Emacs version
in the "Package-Requires" header. It just might use some improvement in
the error message when this dependency is not satisfied.

So, users of all versions of Emacs would use the same latest stable
Gnus, Org and CEDET, as long as the packages maintain backward
compatibility. That would create some pressure to upgrade old Emacs
versions, though (as long as ELPA repositories only contain the latest
versions of packages), but that's not necessarily a bad thing.
