I do agree it probably is limited in the power 'ramp up' and the variables are adjusted there though the 'lag' isn't so pronounced in the rolling test on that video above, he only got a car length in front before the other car was holding.
We know the 2022 RWD has a physically lower rated motor, but in short term peaks (like a 0-100 run) they could probably make it run as fast as the 2021 SR+ if they wanted and think it leaves open the door for a potential paid acceleration boost for the 2022 RWD. As we know the car drive electronics can handle the power and car is physically capable of being safe with 5.6s/100kph acceleration. Brilliant move by Tesla if so, acceleration boost is almost pure profit and many would do it.
The old 'performance' motor in the SR+ would be capable of more than it does as well... I know the one in USA the 3D1 performance motor some company had unlocked the 'ramp up' limitation by the looks:

I've been doing more research on this topic.
I now have more reason to believe they are actually using a lesser 630 Amp rated inverter board combined with the 3D7 motor in the RWD. I was under the impression only the motor changed but possibly not.
While the motor change itself is a physical limitation it generally can take short term peaks above it's rating without issue, an inverter board however is another story this is a hard limitation and would mean an OTA speed boost would just not be possible. 630A inverter board is unconfirmed but likely based on early reports of a car in tests using Scan My Tesla which is showing peaks about dead on 630 Amps which would suggest usage of that board.
If the above is true, how much could this have possibly saved Tesla for cost by downgrading to the lesser motor and inverter board, not a lot, I guess less usage of some components and materials? Probably assumed LR would become more enticing which they would likely make more profit on.
208kW peak, 6.1s/100kmh in the RWD is still a fast car of course, I just find it interesting to investigate since they don't tell us why they made the change.
