There may likely have been issues with die size, power issues, etc. and
yes, given that putting more than 4G on laptops of that vintage would
been unlikely (again for power, motherboard chipset limitation, etc.),
it would be logical *at the time* to ditch 'unnecessary' support logic
on the processor in order to meet other requirements.
And yes, tossing *perfectly working* stuff into landfills is really
dumb. Not an eco-friendly thing to do either. The old machine might
not be useful for current mission critical production purposes, but
could be just fine as an experimental test bed or something else not so
