Fed doesn't like exceptions to the all-but-one. So you guys that want offensive fouls enforced from the previous spot, it's probably not going to happen. To walk you through:
RULE - We have Current All but one
EXCEPTION 1 - Except fouls by the offense behind the LOS are enforced from the previous spot.
EXCEPTION 1.1 - ...except fouls that occur in the end zone. Those are spot fouls and result in a safety. [Note: exceptions to exceptions are the actual rule].
EXCEPTION 1.2 - But it's only fouls like OH and CHB. Illegal batting and illegal kicking and illegal touching are still spot fouls. You have to memorize all of these.
I actually proposed a change (that didn't get past my state office) where if the run ends behind the NZ, the basic spot is the previous spot. This would fix defensive fouls when the run ends behind the NZ (DH on a QB sack), but it would not fix offensive fouls occurring behind the LOS. Those would still be spot fouls. All but one enforcement remains unchanged. Ralph Damren seal of approval

I actually like that the NFHS doesn't let the QB dump the ball OOB to avoid a loss. Defense made a great play. Find a receiver or take the sack.
Here are some of the other proposals I came up with (short short version):
1) Airborne players are in bounds or out of bounds depending on where they left the ground from.
2) 12 men participating at the snap changed to 5 yard illegal substitution (because the only difference between 5 and 15 is how fast the officials can count. That's not right).
3) Editorial change to clarify that the clock goes on the snap... 3-4-3b... "When B or R is awarded a new series
and will next snap the ball." Eliminates confusion of when the ball gets snapped if the down is to be replayed.
4) Kick OOB foul - Editorial change to marry the rule with the case book play - "It is only a foul if the ball becomes out of bounds while on or above out of bounds territory."
5) Clarified for IDP that linemen are allowed 2 yards down field.
6) If you foul while legally spiking the football, the clock goes on the ready. So if you spike it and have an illegal shift, next play goes on the ready.
7) Totally re-worked the IP rule. Too much to type here
