When @Parcelize support was added for sealed classes the final implementation also included support for sealed interfaces, however Lint still gives the following warning for deriving classes:

This class implements Parcelable but does not provide a CREATOR field

Sample snippet:

@Parcelize
sealed interface Foo : Parcelable {
 data object Bar : Foo
 data class Baz(val a: String) : Foo
}

This warning was fixed for the sealed class case in a previous issue, but sealed interfaces still report the warning, requiring the annotation on each child to remove the warning despite the code running successfully with just the parent annotation.
