Really cool!

Perhaps in some cases in action could be, say, (upgrade "1.2").  Though
that’s of course something we can add later.

                                                                      ^
Missing comma.  :-)

> +changes for PACKAGE, or #f and #f when PACKAGE is up-to-date.  KEY-DOWNLOAD
                                   ^
Instead of “, or …”:

  ; return #f (three values) when PACKAGE is up-to-date.

Otherwise LGTM, thanks!
