I don't think it's *total* FUD, tough I agree with you that "it" is doable
and will continue to be done.  However, "it" also caused a bunch of code 
to break on architectured where strict alignment matters because the data
is returned packed and sometimes simply walking a ifreq pointer through
the buffer is not TRT, IIRC.
