You might be interested in the following guix-daemon options:

      --gc-keep-derivations[=yes/no]
                             tell whether the GC must keep derivations
                             corresponding to live outputs
      --gc-keep-outputs[=yes/no]   tell whether the GC must keep outputs of
                             live derivations

Perhaps by setting them to "yes", you can avoid collecting store items
that you'd rather keep around.  I think these default to "no".
