What I meant is that the version string alone is insufficient. You can
have multiple variants of a package with the same nominal version, but
the differences are in the closure of the package. When Guix is
upgraded in between two invocations of “guix package -u” seeing the same
“version” of a package to be upgraded to is a common occurrence.

That bit of information was not available to me when I composed my
initial response. If Guix is not changed in between then this behaviour
seems to be a bug.
