It is implicitly documented if you know that dpkg/dselect use in their
available file only one version -- that is why we print only the candidate,
so this is not a issue with experimental, but a general only one version
per architecture for a package.
Why do you need that information? And why is simple cat'ing the Packages
files in /var/lib/apt/lists together not an option? (okay, not failsafe,
as it will not work with file:///, but beside that it should be fine)
I guess it should be easy to get it with some lines out of python-apt or
with "misusing" EDSP (apt-get dist-upgrade -s --solver=dump) which has
a similar format. Both should be faster than: apt-cache show .*
(if multi-arch is involved, you have to say .*:arch1 .*:arch2 …
as arch globing doesn't work yet if we deal with packagename regexes)
Depends a bit on how and why you need that info at all though.
