I'm using regularly `guix gc -d /gnu/store/...` and I'm a bit concerned
about re/abusing this existing parameter. First I like the simple '-d'
to delete a store path. Second, how big is the chance I could
accidentally delete (all) older generations of my profiles? I really
like to keep them for a long time, until my disk is near-full, and it
looks like gc-roots are no longer a safe way to keep them?
