Exactly - they will stop awarding "pollution-reduction credits" for installing this non-mandated and optional to use feature.
There is absolutely nothing preventing automakers from keeping this feature in future car models...
And most of them will as it's less about pollution and more about cutting fuel usage... Which lets them get that MPG (or L/100KM) figure down in sales brochures. Also most other countries are going to keep the requirement and the US will adopt it when the current government finally collapses.
The bigger the engine, the more you notice the fuel consumption dropping, I had a BMW M240i and it was easy to keep the system from kicking in (just hold down the clutch... most steering wheel attendants will need to ask a real driver what that is) and the difference was a good couple of (British) MPGs over a 30 minute in town commute (a lot of stop-start). The fact was back in 2017 the system was good enough that I never bothered disabling it permanently as it was practically instant (and if I wanted to start the engine earlier, I could just use the clutch). This was a German 3L turbo, I imagine the difference it makes on an American engine would be even greater.
