Should we also stop calling negative numbers numbers?

Maybe. Consider for example Hossack (2020) Knowledge and Philosophy of Number. He indeed lays out a framework in which negative "numbers" aren't considered numbers, precisely because negative numbers combine a magnitude with a direction.

Let's throw out every textbook and start over, then.

Maybe we should. Irrespective of any concerns on the philosophical underpinnings of mathematics, there is an active discourse on the shortcomings of pedagogical resources. See for example Hung-Hsi Wu and his negative view of "Textbook School Mathematics (TSM)". His critique is aimed at the US. I am unfamiliar with any cohesive argumentation across for example European curricula.
