As mentioned in the thread for GIP-0031, this has been voted by the Council on Snapshot; the implementation for the L2 bridge has passed all the audit rounds and we’re almost done with testing. So we’re now working to get the L2 protocol, that includes the change proposed in this GIP, deployed soon.
Worth noting that this initial L2 deployment won’t include indexer rewards yet, and that Howard and team are still working on a Curation v2.0 proposal that would solve the issues that persist in this v1.x.
