We have updated the proposal to version 2.0.0. Notably, this includes removing the storage-related pricing changes - SSTORE and CREATE(2) op code pricing now match Ethereum. Refunds have been zeroed out as is currently the case on the test networks (full charge on the gas limit). The decision to remove the storage pricing changes from the proposal is in the interest of mitigating potential disruption in the short-term. We anticipate sharing a comprehensive design proposal for state economics in the near future for feedback. That proposal should similarly incentivize healthy state hygiene.
