Except going slower means you can stop faster, and considerably more so than the linear progression of time. So really the undue burden must be on people going straight through the intersection at the speed limit.

From the journal article:

"GHM’s solution to regulate a yellow change interval first appeared in the 1965 ITE Traffic Engineering Handbook, and it has become known as the kinematic equation. However, GHM’s solution is limited to vehicles traveling through level intersections at constant velocity, which does not include vehicle deceleration to execute safe turning maneuvers. This article presents a brief review covering GHM’s original solution and Mats Järlström’s extended kinematic equation which allows for vehicle deceleration and turning maneuvers."

By the time the yellow comes up, you've already made the go/no go decision, and you are scanning for pedestrians and other cars. You don't even see the yellow.
