We’re not _quite_ ready to say **stable** , but we will be making them available to users in the very near future! Then after a period of customer exposure, marking them as stable.

They’ve been sitting as PRs for a long time upstream. I’m optimistic that by putting them in front of more users, we’ll get more feedback and operational experience faster.
