I think a longer fence helps keep long stock properly aligned for the cut.

Who cares if the stock is aligned to the back of the fence BEHIND the
blade - it's already been cut.


Dadoing and rabbetting.

If the stock moves at back of the blade, it can mess up the end of the
dado or rabbet.


Two points for the correct answer. And become dangerous as you might
pivot off the end of the fence, exposing the cutter.

Also 4' x 8' panels are much easier to control through the cut with a
longer fence.

The analysis that the dimension of the cut is determined only by the
fence that is in front of and adjacent to the blade is accurate.

Rear locking fences tend to have short fence blocks and shouldn't
required constant checking to insure blade alignment if properly
designed and adjusted the first time. Fences that lock on the front
only, depend on the wide stance of their t square fence bodies
contacting very stout guide rails. They should not need to be locked
in the rear.

Other than that, I agree with the short fence concept.
