/hold for comment

also might best wait to land this change until after 1.5 - since we can mention this in the release notes/mailing list

One question that I think was asked before is whether this could be useful for quick debugging at the queue proxy side, especially for contributors?

If this is the case then I think we could simply just json marshal the stat vs. having a full fledge prometheus endpoint.

We also have user facing metrics - https://knative.dev/docs/serving/services/service-metrics/

@nader-ziada did we let enough time pass for comment on whether to go forward removing this?

I think it should be fine to merge this. Probably worthwhile to send a note to knative-dev announcing that we're removing it, then we can merge later this week.
