No, I don't know if there are any CSS (contact start/stop) drives being made any more. Those are the ones where the heads will land on the media during spin up/down to park. This type of design is more sensitive to non-op shock, as the shock impulse goes directly into the slider. Also, the act of parking causes a slight amount of wear, which is why you'd typically see things like park cycles rated for 50K vs. 300K (or more) for rampload drives.
Pre-emptive wear leveling is a way to distribute the grease in the pivot bearings. Since bearings are usually designed for 360deg of motion, but only go through ~60deg of travel in a drive, the internal grease can build up on both ends of the stroke. Over enough cycles, this can cause a problem if you have to turn off power to the drive and park the heads, as the actuator has to have enough "oomph" from the back EMF to go over the bump. Something similar can happen with media lube build-up with time, though I don't know if this wear-leveling is also meant to spread out media lube.
