I want to say Honda didn't install them on their D15 engines, but the slightly longer stroke D16 (and every engine of larger displacement) got one.

I had to check, and the Insight's 1.0L 3 cylinder has a harmonic damper. That surprised me a bit as I imagine it's probably an accessory loss, turning some crank motion into heat.

Maybe all timing chain motors have one? I could see a belt as providing some damping.
