I've opted to punt on these other patches for now, just out of caution
of introducing sizable changes right before release.

But for 1.14.4, we should probably either finalize our decision to
remove 10.4 support, or restore it and commit to maintaining it for some
period (maybe until 1.16?)  Andrea and Toshiyasan, please find a
consensus between the two of you for what approach we should take, and
we'll revisit this.

Thanks,
