This reduces the object graph returned by:
guix graph -e '(@@ (gnu packages commencement) glibc-final-with-bootstrap-bash)
from 333 nodes (1542 edges) to 148 nodes (886 edges).
This improves 'package-derivation' memoization and, consequently, the
'add-data-to-store' cache shown by:
GUIX_PROFILING=add-data-to-store-cache guix build coreutils -nd
goes from 10948 lookups to 8935 lookups.
