This doesn't have any immediate uses, but this adapts the code a bit more to `Core::Stream` conventions (as most functions there use NonnullOwnPtr to handle streams) and it makes it a bit clearer that this pointer isn't actually supposed to be null. In fact, MP3LoaderPlugin and FlacLoaderPlugin apparently forgot to check for that completely before starting to decode data.
