Actually, there is. You'll end up riding the brakes more during the downhill
thus causing unnecessary wear to the pads.
The Prius knows exactly what to do with any excess energy during long
downhills, whether the battery is fully charged or not. Shifting to neutral
and coasting downhill is leftover from your grandparents' legacy. There
is absolutely no technical or logical justification for it.

Hold on. If you say that it's not the compression but the rpms that causes wear, and the Prius has no true neutral, so the engine is spinning whether it's in...

A modern engine just "spinning" and not generating power would create so little wear that I doubt it would be measurable over 2 or 3 car life times. No heavy...
