People write whatever games they want, and they call whatever games they want roguelike. If someone (the creator or otherwise) thinks that a game isn't a roguelike by their own definition, and if they see some elements of a roguelike game or hear someone else say it's a roguelike(like), they might call it a roguelikelike.
Berlin interpretation aside, both concepts have such variable meaning in the wider game community that they're not very precisely descriptive outside of small, like-thinking groups or one's own head.
