I have a project where the `stack.yaml` specifies `ghc-options`: https://github.com/NorfairKing/smos/blob/development/stack.yaml#L31-L32 The project has both a nix build and a stack build The nix build passes: https://github.com/NorfairKing/smos/actions/runs/219360286 The stack build does not: https://github.com/NorfairKing/smos/actions/runs/219360285 I expected the nix build to fail as well.
