The POH definitely helped, as will the sybil report, but I still feel the main goal of having a min threshold would be to eliminate sybils (particularly ones that botted Linea after 4844).
If we were able to know for sure that someone is a human and they only contributed a little bit to Linea, I still think they should be rewarded. But this isn’t the reality due to the pseudonymous nature of blockchain atm, so I understand the arguments for including the threshold.
