Regarding the QA:
TBH I don't fully get the damping factor logic, but in case it affects only the token rewards but not the points I'm worried it might break the reward history calculated on both Pioneer and the polkadotjs app which would be bad since AFAIK these are the 2 main sources of truth regarding validator rewards.

@thesan the rewards multiplier should indeed only affect the token rewards, not the era points. Could you share more about what that would break?
