Since V2 is an upgrade of V1, its versioning should be updated to reflect the upgrade as well. It is important for the correct version to be reflected since it also part of the EIP712 data to be signed, which is used by EIP2612 and EIP3009 for fungible asset transfer authorizations. Authorizations given for outdated versions should rightfully be made invalid.
