Why would we stop caring about backwards compatibility? If I was a user
of any of the platforms in question and updated my kernel, I wouldn't
expect to have to debug why it was broken, then install a new dtb to fix
it - which may be a tricky thing to do, depending on the firmware used
to boot Linux.
