A lot of flakes set local substituters in the flake.nix directly, and if we are going to use the json to decide whether or not to build a derivation we should use this project specific caches directly, at least when evaluating a flake with --flake.
It might also be useful to list which caches the derivation exists in to help in cases like #139
