If you do, once coding begins please list all relevant k/k PRs in this issue so they can be tracked properly. 👍

Thanks!

[wojtek-t]

Yes - this is planned for 1.17

[mrbobbytables]

Great. I'll add it to the tracking sheet 👍

[wojtek-t]

Given it's not a feature per-se (this is implementation detail, the change is invisible to use), this will go directly to GA. Changing the stage.

[wojtek-t]

We're already code-complete for that. And given it's purely implementational change, it doesn't require any docs.
Which mean that we seem to be completely done with it.

[mrbobbytables]

Nice! Just for accounting purposes, was this the primary PR?
https://github.com/kubernetes/kubernetes/pull/81914

[wojtek-t]

Yes - https://github.com/kubernetes/kubernetes/pull/81914 is the main one.
https://github.com/kubernetes/kubernetes/pull/84043 is some minor improvement on top of it.

Hello @wojtek-t I'm 1.17 docs lead.

Does this enhancement (or the work planned for v1.17) require any new docs (or modifications to existing docs)? If not, can you please update the 1.17 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-1.17) due by Friday, November 8th, it can just be a placeholder PR at this time. Let me know if you have any questions!

See the comment above (my second last comment):

This KEP has been implemented and released in 1.17. Closing.
