For what it's worth, I think you will be able to ship via 2024 QBDT as the old ship module/method will continue to be available -- just not in 2022 and older.
And, yes, I agree we are forced by Intuit to upgrade every three years. It wasn't until today that I fully understood the New Ship Manager obsolescence was really for 2022 version, and the old shipping module will still work in 2024 (maybe even 2023 version) after 31-May-2025.
I am guessing the new Shipping Manager will never be available to QBDT versions older than 2024.
