Yup! The difference is significant primarily for profiles with lots of
propagated inputs, so typically profiles with R or Python packages.
For my home profile (300+ packages but no R and no Python), it goes from
316K to 112K, heap usage for ‘guix package -I’ goes from 12M to 9M and
wall-clock time is almost unchanged.
