The better way to rephrase this from a technical perspective is:

I don't care about udev firmware upload as it'll be removed, and its only
adding 60 second delays. I *know* this driver doesn't require custom paths and
wierd user upload tools so lets evolve a few light years ahead and embrace
non-udev Direct upload for at least optional juju config data.
