We likely won't support it until it is promoted to stable.

It may also be good to document the package structure.

Ideally we would only scrape native histograms if the feature flag is enabled, and only scrape classic histograms if scrape_classic_histograms is set.

IIUC, the sum should not be reported if it includes negative observations (at least for "standard" histograms, since sum is a counter). https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md#histogram. Is sum not required to be monotonic...

If testing will take more time, we can always merge it behind an alpha feature-gate to give time for testing. That way you don't need to keep rebasing it.
