Bonding to the lighting circuit's CPC is not required if the light and

No, the CPCs of circuits feeding equipment within the Zones should be
bonded, even if all such equipment is Class 2. That was one of the
significant changes made when the new bathroom rules were introduced in
2000. I've always assumed it's so that the bonding is already in place
for when replacement Class 1 fittings get installed.
