I actually have no issues with whatever classifier someone decides
to use. To each their poison. But I do take issue mandating the
specified classifer it as THE CLASSIFIER as in this case,
is where i start taking issue. I have a few things that i offload
to hardware with speacilized classifiers such that i object strongly
to the approach this driver has taken.
