FWIW I think it’s reasonable for ‘--help’ to be generally more concise
than the manual.  We could list the possible strategies here, but that
might clutter the output more than is desirable.

Improvements are always welcome of course.  The main criterion would be
to remain consistent with the rest of Guix and with GNU conventions that
we follow.  Maybe it’s best to discuss what you have in mind first?

Thank you,
