Suggested change
| type MaxValidatorsPayout = MaxValidatorsPayout; |
If you were to do this approach, I don't think there is any need to pass MaxValidatorsPayout to the staking pallet. Whatever cap is needed, should already be applied to RewardCurve or whatever type is implementing type EraPayout.

A bit wrong because of https://github.com/paritytech/polkadot-sdk/pull/1859/files#r1382983349, but in any case we probably won't need it.

This PR implements an (optional) cap of the era inflation that is allocated to staking rewards. This mechanism can be used to guarantee a minimum treasury inflow as per this discussion.
The (percent) maximum validators payout can be set through
SystemCall::set_storage.Note: The
storageparameter type in the runtime configs only sets the pre-set_storagedefault value. Once the value is set on-chain, the default will be a noop and not anymore a source of truth.Todo (once merged)
era_payoutimpl included)Related to and possibly replacing #1660
Closes #403
