Actually I rather do kind of doubt that. Look for instance at what's proposed now for drivers/isdn which realistically, could have been in drivers/net. Also, various bits of hardware support have already been dropped from drivers/net. The 3c503, ni52 and others come to mind. Token Ring support too.

I do understand your concern. Backporting patches to obsolete hardware shouldn't much be necessary as obsolete hardware, as you wrote yourself, simply doens't get much testing. Archaic stuff should eventually get sifted out altogether. Marking drivers as archaic at least allows people that use use the older devices to object and maybe actually step up to maintain them too.
