I think parent is more getting at component lifetime. Every charge/discharge on the batteries is a bit of their lifespan gone.

Although I was under the impression that the impact on lifespan is much greater the deeper you cycle the batteries, so it might be better to be perpetually topping them up.

Yeah deeper cycle reduced life - highway static travel speed would idle onboard capacitor bank.

You make me wonder if it would be better to charge every hundred miles in your 250mi range rated EV as a way to preserve long term battry health on a long interstate road trip.
