+Instead of only being able to toggle the use of [Import from
+Derivation](https://nix.dev/manual/nix/stable/language/import-from-derivation) with
+`allow-import-from-derivation`, Lix is now able to warn users whenever IFD is encountered with
+`warn-import-from-derivation`.

+By default, Lix allows you to `import` from a derivation, allowing
+building at evaluation time. With this option set to true, Lix will
+throw a warning when evaluating an expression that uses this feature,
+allowing users to know when their evaluation will requires any builds
+to take place.
+
+This option has no effect when `allow-import-from-derivation` is `false`.
