Also I would think that if machines with more than one core profit while
those with only one core will be slightly slower is a good trade of
given that almost any machine from the last 20 years contains more than
one core.

In general Emacs shouldn't hold back to support very old legacy systems
on the cost of any recentish system from the last 10 years or less from
my point of view.

In case there's still the builtin gc..
