Hey @BrianMMcClain,

I've seen this one pop this morning but am only commenting now (sorry), just to let you know, the documentation for this feature is baked into the PR that introduces the code for the feature (in a separate branch, refer to PR #13171, which is still marked as [POC], but is very much not anymore so).
Regarding those documentation changes, would it be possible to amend this PR instead?

@lbajolet-hashicorp Ah good call, totally missed there were docs included in that draft, my bad! Closing this one and drafting a new PR against that branch now :)
