Hey @neolit123 @fabriziopandini

I'm one of the v1.16 docs shadows.
Does this enhancement (or the work planned for v1.16) require any new docs (or modifications to existing docs)? If not, can you please update the 1.16 Enhancement Tracker Sheet (or let me know and I’ll do so)

If so, just a friendly reminder we're looking for a PR against k/website (branch dev-1.16) due by Friday, August 23rd, it can just be a placeholder PR at this time. Let me know if you have any questions!

yes, it does require docs.

i've added a placeholder docs PRs: TODO note in the OP.
we will definitely create place holder PRs before the 23rd.

thanks for the heads up!

@sethmccombs

hi, we spoke about whether this requires docs again during the office hours of kubeadm (Wed 21Aug) and decided to not add any documentation for this feature's Alpha stage.

i will defer to @fabriziopandini if we decide to change our mind later down the line.

i've also updated the OP with some WIP/merged PRs.
thanks
