The fact that we have 2 versions is the answer.  In Emacs UI a package
is not considered to be obsolete if there is a package definition with
the same name+version.

That's why "texinfo 6.0" is green in the list, not red (as obsolete
packages).

I believe marking such packages as obsolete is not correct and it may be
confusing.  See <https://gnunet.org/bot/log/guix/2016-02-09#T909651>.

For example, if a user makes a package for some old version, (s)he wants
to use it and probably doesn't want it to be updated by accident
(because it is obsolete).
