I like this proposed change. With this in place Adaptive Issuance (AI) starts to make much more sense as a way to minimize emissions while preserving an adequate level of protocol security.
In addition to the progressive minimum rate, we should seriously look at the staker/delegator reward split. If protocol security is what we seek ultimately, rewarding delegators with 50% of the staking rewards doesn’t make sense, especially in the medium-to-long term, if IA is to accomplish its goal.
I think a good place to start is reducing delegator rewards by 33% and putting them into staking rewards.
