The belt could possibly get chewed up faster, but serpentine belts are flexible and I want to say a little bit of vibration wouldn't kill them.

I agree. When I research aftermarket crank pulleys, or milling mine, to reduce rotational mass, I ran into these debates. But these little four cylinders and the RPMs we're runni g them at... not much risk. The OEMs, bless 'em, overbuild... just the way I like my Hondas... overbuilt by the OEMs. I did not add the lightweight pulley in the end (price and availability).
