The risk here is that we expose a preexisting bug in some CPU side
driver to a wider set of users, but those drivers would still be buggy
no matter what and may already be causing problems on some systems even
if that's not been reported so if there is a problem it's always
possible that we end up helping some users who currently have issues by
helping someone realise what the problem is.  However most likely nobody
will notice anything either way and most systems will continue using
exactly the same formats they already were.
