The intensional model (content-address item) works well if and only if packages are 100% bit-reproducible, which they are not (yet!). Also I=E2=80=99m not sure how substitutes could work with this model since = one cannot refer to the build result until it=E2=80=99s available. My guesses! Ludo=E2=80=99.
