That's a use case.  While --dry-run exists, I don't really want it to
serve double duty here.  If I previously guix pulled and only three new
packages were added, none of which I'm interested in, I would not have
to meaninglessly run further build commands like guix package or guix
system.  Even if the list is potentially longer, I could visually grep
for a few packages I'm interested in and determine whether it'd make
sense to build now or wait for a little while as I'm processing other
things.

In general, it doesn't have to be named ‘--news --details’, but a means
of diffing two generations via the CLI -- in particular the current one
to the last -- would be very welcome, because then all information we
previously had would still be available quite easily, albeit no longer
printed by default.
