KSDeclaration.isOpen for interfaces returns false

[yigit]

The isOpen check for an interface returns false but i think it should return true since isOpen can be used to check if something can be overridden / extended.

the following code assumes KSDeclaration is NOT as it only checks for parent for checking interfaces, not the declaration itself.

fun KSDeclaration.isOpen() = !this.isLocal()
        && (this.modifiers.contains(Modifier.OVERRIDE)
        || this.modifiers.contains(Modifier.ABSTRACT)
        || this.modifiers.contains(Modifier.OPEN)
        || (this.parentDeclaration as? KSClassDeclaration)?.classKind == ClassKind.INTERFACE
        || (!this.modifiers.contains(Modifier.FINAL) && this.origin == Origin.JAVA)
        )
