I think we need to allow for packages to work with this. I.e. drop files into config directories rather than require editing of config files. I think this is mostly workable via modprobe.d.
(for our own use case, we don't require the extreme performance of many L2/L3 dpdk apps so we'll work with regular iommued vfio for bare-metal installations and ship prebuilt virtual machine images for clouds, so it doesn't matter that much to me).
