is this a bug? the `get_starting_replication_key_value()` stream <https://gitlab.com/meltano/sdk/-/blob/main/singer_sdk/streams/core.py#L188-L190|method> claims the `context` param is optional but the function call to `self.get_context_state()` right below seems to require that param.

On the surface it looks like it is functioning as designed. Perhaps what is less clear is that `get_context_state()` returns the top-level stream state if context is `None` .

Most of these arguments are designed where a context of `None` _is_ a valid context, just the top-level context (meaning the total stream).
