The "locks out tuners" bit is pure click-bait non-sense. Tuners will either work around the sensors (as they have for decades) or replace the ECU with any number of aftermarket models.
Although with turbocharged engines, you can turn the power up to the point where longevity goes way down. Still, you could give people a power limit knob they could turn at their own risk to have access to the whole Pareto frontier of performance and longevity. That'd leave no room for tuners.
Secondly, there’s a reason you see this with EVs (Tesla’s “ludicrous speed” mode) but not ICE cars apart from “sport modes” and the like: the ICE cars can’t be offered with the knob you suggest, because the car has to meet emissions requirements at any tuning level, and any level of tuning is going to have a performance/emissions trade-off.
Depends on the car. See Supplemental Federal Test Procedure US06[0], required by the EPA for light-duty vehicle certification since 2007.
It is also largely irrelevant in the real world: nobody is going to tune a car to have mediocre part-throttle performance but then go all-out on full-throttle.
