"iOS 11.3 and later improve this performance management feature"
and
"iPhone 8 and later use a more advanced hardware and software ..[snip].. As a result, the impacts of performance management may be less noticeable on iPhone 8 and later."

It is true that Apple was only targeting phones with dodgy(to a degree of approximation) batteries.
OTOH, Apple does a better job now. Both in execution and communication.
Whether Apple would have reached this achievement without batterygate is unknowable.
My apologies for spreading misinformation, thank you for your patience.
