So when you upstream them, the binding becomes wrong or not needed?
Sorry, bindings are entirely independent of OS, so using this as an
argument is clear no-go.

None of this explains any hardware related part of this binding. You
created now policy for one specific OS. Devicetree, which is OS
independent, is not for such purposes.
