And unrelated to this patch set, let also mention this other thread [1],
comparing (btrfs):

Compared to (ext4):

--8<---------------cut here---------------start------------->8---
145M /gnu/store/nqrb3g4l59wd74w8mr9v0b992bj2sd1w-guix-d62c9b267-modules/lib/guile/3.0/site-ccache/gnu
117M /gnu/store/s6rqlhqr750k44ynkqqj5mwjj2cs2yln-guix-a09968565-modules/lib/guile/3.0/site-ccache/gnu
--8<---------------cut here---------------end--------------->8---

Somehow, these packages .go files could be compressed and decompressed
on the fly when needed.

Cheers,
simon
