This isn't changing the semantics for all drivers, it means it leaves
it up to us to fix the drivers that hit the problem. Whereas the other
way round we'd have to make some fairly big modifications to a large
number of drivers, which the driver maintainers are likely to be
reluctant to accept and maintain. It will be a constant chase to keep
that in order.
