I didn't get the sense that WJW is unfamiliar with the industry. I read their comment as suggesting that the administrators who designed the existing regulations did so at a time when the widely understood definition of "miner" was a proof-of-work miner. If the same regulations were drafted today, would PoS validator nodes be considered functionally equivalent to PoW miner nodes? I hope not, since they aren't.
