The motivation for this change is to enable a new Dhall command-line utility called `dhall-to-nixpkgs` which converts Dhall packages to buildable Nix packages. You can think of `dhall-to-nixpkgs` as the Dhall analog of `cabal2nix`. You can find the matching pull request for `dhall-to-nixpkgs` here: https://github.com/dhall-lang/dhall-haskell/pull/1826 The two main changes required to support `dhall-to-nixpkgs` are: * Two new `buildDhall{Directory,GitHub}Package` utilities are added `dhall-to-nixpkgs` uses these in the generated output * `pkgs.dhallPackages` now selects a default version for each package using the `prefer` utility All other versions are still buildable via a `passthru` attribute
