Upon reviewing the board report template, I am planning on the following schedule: 1. I'll leave this proposal for another few weeks to gather any additional input 2. In early February 2024 I'll start a formal vote thread on the dev@ mailing list for this proposal 3. If the vote passes, I'll submit a proposed resolution to the ASF board for their meeting in April 2024 using the pre-existing template[1]
