GrapheneOS is an open-source fork of AOSP. Anyone could fork it again and provide kernel modules/drivers for their hardware.
To my knowledge, GrapheneOS is not standards-based. They take one operating system, and tweak it. I don’t know if there are relevant standards to contribute to, or even standards bodies to approve them.





it doesn’t ship with grapheneOS, it just has support for it. I imagine the stock android it ships with will be riddled, though
