Excellent shout with commission updates. I am leaning on the side of caution given the issues that Westend presented to us recently. Perhaps for now we can leave Polkadot alone, and closely monitor / test on Kusama - where GlobalMaxCommission is 10%.
If this discussion / proposal requires more time then these thoughts assume and we manage to carry out commission testing prior to this proposal going live, then we could open the door for combining.
