Lix simply emits all warnings to stderr. All warnings it emits are deprecation warnings which we would like to turn into hard errors in the future, but are still too widespread in use, including in Nixpkgs. If we don't hard-error on these too, then regressions will continue being introduced and we will never be able to turn these into hard errors.
