Yup, that is one thing he can do, contribute to the existing kano fork, however, it seems like for many years Kano is the sole contributor of that repo, so i am not sure if there is much that needs doing.

Also, who actually benefits from it? sidehack and maybe a few usb miner's manufacturer, those do deserve it, who else? Bitmain? they maintain their own shit, other custom firmware makers?
