Indeed, it’s not dangerous, and I don’t think the manual suggests that.

To avoid collecting things just to redownload/rebuild them later, I
usually ask ‘guix gc’ to free up some amount of space, as in:

  guix gc -F20G

That ensures 20G (more or less) are available on my disk and doesn’t try
to collect more than that.

Thanks,
Ludo’.
