See #13570 for details --- the idea is that included the store dir in store paths makes systematic JSON parting with e.g. Serde, Aeson, nlohmann, or similiar harder. After talking to Eelco, we are changing the `Derivation` format right away because not only is `nix derivation` technically experimental, we think it is also less widely used in practice than, say, `nix path-info`. Progress on #13570
