Some of the replies on this thread lead me to believe that there's still hope.
I'll send another check-in and see if anything comes back.
Feels reasonable to expect some response, even if it's just boilerplate.
For what it's worth, the survey was asking whether to ship now, wait for now and be emailed again after the next batch, or wait until the end.
I chose to wait for now, thinking I'd have them ship the next batch and then each following until the end.
That was September 2023.
