Since there is no package private in Kotlin, how do you deal with situations like this:

class SomeUseCase(//dependencies) {
    sealed class Error {
        object NetworkError : Error()
        object NoResultFound : Error()
    }
    sealed class Success {
        object OneSuccess : Success()
        object TwoSuccess : Success()
    }
    suspend operator fun invoke(): Either<Error, Success> {//code}
}

Where each out of many use cases may have their own domain error/success cases but then we have Success or Error pollute the entire code-base namespace which makes it a bit annoying to work with.
I know the internal modifier exists but for various reasons we can’t just modularize our codebase, at least not instantaneously.
In Java I’d slap a package private in there and call it a day, does anyone have any tips on how to model this nicer?
