I beg to differ, accidentally (forgot to actually enable periodic GC)
had a 6.4 TB large Nix store on a 3 TB disk array, so it seems that the
Nix store (or at least the one on my Hydra) compresses well enough.
But what actually is going to be for the worse is that you can't reason
anymore about how much disk space will be available on a btrfs volume.
