What should be the guidance for backend/devices here? Go with version 3 only if
it requires driver to poll on reset? Otherwise it may break existing setups -
lets say Qemu is updated to report version 3 which will break older guest images
that understood version 2 - this is despite the same Qemu being capable of
serving those guests.
