Just to be clear, I agree with you, Mark.  Guix shouldn't delete GC
roots automatically by default.  I think we were just saying that it
might be nice if a user could configure Guix to automatically delete GC
roots according to some policy (e.g., retain the last 2, and delete any
others older than 1 month).  Guix would only delete the GC roots
according to the policy that the user has set, and if no policy has been
set, the default would be not to delete any of the GC roots.
