Hi everyone, We hope to include this FLIP in the 2.0 version, which has a feature freeze date of January 20th. To allow enough time for code review, we plan to start the vote today.
If you have any questions or concerns, please feel free to ask them in this discussion thread. We will respond as soon as possible. Thanks for your understanding.
