I usually run ‘guix gc -F 4G’ or similar, which removes just as much as
needed.  That works rather well for me.

They “need” to be downloaded again only if you want to rebuild them,
yet without adding them to a profile or making them a GC root.  :-)

When needed, you can explicitly protect things from GC using profiles,
or using ‘guix build -r’.
