Sorry for the late review request @wojtek-t

please @dashpole make sure to use the latest KEP template. The template is periodically updated and if the lastest update of the KEP was more than a couple cycles old there can be some changes to be made

Some very minor comments but don't want them to slip through the cracks:

Some sections in the PRR Questionaire are still marked as TBD (e.g, Are there any missing metrics that would be useful to have to improve observability ).

Also, I see there are plans to add metrics but metric section is TBD in kep.yaml.

[dashpole]

@swatisehgal @ffromani I updated the KEP to use the new template.

We are blocked adding metrics by work in upstream OpenTelemetry. But traces are themselves an observability signal, and can be used to see if the feature is working properly. I don't think metrics should block the GA of this feature

Two minor comments - other than that LGTM.
But please work on having SIG approval first.

[ffromani]

pretty much LGTM from sig-node, few thoughts inline

LGTM also from sig-node. I think pending open points are on PRR side.
