with a commercial aircraft there should be no actual reason for not giving it the best possible stability and ease of control

Apparently, the 737 was originally a smallish plane designed for regional airports. It had short landing gear so it was convenient for places without boarding ramps.

After many changes and upgrades, Boeing reached the point where they needed a model with more economical engines. But they couldn't fit new high-bypass engines under the wing. They couldn't make the landing gear taller because of the way it retracts, so the engines had to be moved forward. This pushes the nose up under maximum power. There's a suggestion that when the nose goes up the fat nacelles themselves produce lift, which pushes the nose up even more. This is the instability they were trying to disguise.
