I don't like the idea of this control being in the hands of the SPO. It is not transparent. This type of control may come with unnecessary responsibility - stake pools could decline. This opens up more questions for me. How will this impact performance? Will it lead to more regulation at this level? Are there alternatives? What are the alternatives? Can we vote on alternatives? Does KYC integrate with this? Is it really necessary at this time? Are SPOs really complaining? What's the big picture?
