I don't understand how this proposal can survive even momentary
consideration.  We're going to cut off some nontrivial fraction
of our userbase to get 1-2% speedup for the rest?

As was already mentioned, the people who need speed are probably
on x86_64 already.  The x86 builds are for legacy hardware *now*,
and should be understood as such.
