Accuracy, very much like "beauty" is, "often in the eye of the beholder". Presuming a QB, tackled by the face mask, is downed where the foul takes place, the spot of the foul IS the end of the run, so there really is no need to invoke an "All but one" adjustment.

When the defense has accomplished reaching the QB, or any runner behind the LOS without benefit of ANY illegal act, they are entitled to whatever yardage advantage they have legally attained.

Conversely, when the defense has legally forced the offense to retreat 10, or more yards, behind the LOS their is NO CONSEQUENCE to the offence choosing to foul, and in addition to the loss of yardage being the same, or less, (depending on the offensive foul selected) they gain, what some consider an UNFAIR advantage of replaying the down, when the penalty is accepted. In essence, the offense is ENCOURAGED to foul, as the penalty for doing so is negated by enforcing the penalty for fouling from the previous spot.

Much like "beauty", "stubbornness" is also, "often in the eye of the beholder.
