I tried to be consistent with that but as you noted there is no way to
mark a single package for upgrading there.  Also there is no key binding
for unmarking everything and no such thing as "general mark".  In
“guix.el” you can mark several packages with "m" and then press "RET" to
describe those.

I like this variant, but I have a question here.  I'll ask it in a reply
to Ludo's message.

Originally “package.el” wasn't generalized.  But when it became a part
of Emacs, “tabulated-list.el” was extracted from it and now
tabulated-list is required by “package.el”.  “guix.el” uses
tabulated-list as well.  There is no way to use package-menu directly as
it is too specific for Emacs packages tasks.
