Pinging @elastic/es-docs (Team:Docs)

[jrodewig]

Approved. The text could be improved, but I don't think we should block the release over it.

[jrodewig]

The text for this attribute doesn't really make sense here:

This feature is in development and not yet available for use. This documentation is provided for informational purposes only.

There is no "documentation" in this case.

[lcawl]

True. I thought that was a better stop-gap than referring to master docs for now, but hopefully there will be a quick fix and we can remove these redirects entirely.

[jrodewig]

@lcawl I'm going to merge this in and kick off a fresh build for elastic/docs#2722.

Thanks again!
