Cool!  Could you do (or anyone else with btrfs),

    guix time-machine --commit=d62c9b2671be55ae0305bebfda17b595f33797f2 \
         -- describe
    guix time-machine --commit=a099685659b4bfa6b3218f84953cbb7ff9e88063 \
         -- describe

then report the size (compsize) of

/gnu/store/nqrb3g4l59wd74w8mr9v0b992bj2sd1w-guix-d62c9b267-modules/lib/guile/3.0/site-ccache/gnu
/gnu/store/s6rqlhqr750k44ynkqqj5mwjj2cs2yln-guix-a09968565-modules/lib/guile/3.0/site-ccache/gnu

?
