The existing mapping is ABI. Users do not expect their devices to
suddenly move around. If the driver hadn't been merged yet I'd not
object to the concept. However it is now years too late.

Remap it in userspace if you want, add udev rules for it if you like,
but the kernel mapping is set in stone.
