- * We want to explicitly set all optional (Maybe) AppSpec fields to `undefined`
- * (instead of using an optional field with a questionmark).
+ * We use this type for fields that are optional (Maybe) in AppSpec.

+ * to explicitly set the field to `undefined`.
  *
- * Doing so doesn't change any functionality and ensures (at compile-time) we

+ * This way, if the AppSpec changes on the Haskell side, we won't forget to
+ * implement a proper mapping in TypeScript.

  * For example, let's say `bar` is optional (both for the user and for the app
  * spec). This would be the correct mapping code:
