This thread has some of the math in it: Shuffling node memberships of subnets: an exploratory conversation
Oh wait, maybe the math didn’t show what I thought it showed…see for yourself I suppose. I’m not convinced it’s a bad idea, and the fact that others whose opinions I highly regard on the matter seem to agree then I am very much still on board with node rotation.
If we have a conclusive analysis that it’s dangerous then I’ll be done with the idea, but I highly doubt such an analysis would end up that way considering the fundamental importance of shuffling in other designs e.g. Ethereum.
