That's not universally true, both battery chemistries are in use and still being sold new (I believe the smaller batteries are using the new "100% safe" chemistry, while the long range variants are using the "keep the charge around 70-80%" chemistry.) The car will alert you if it's not safe to charge frequently to 100% when you set the charge limit.
