Thank you for this PR! Could the warning also be added to the docs-level rst?: https://github.com/open-telemetry/opentelemetry-python/blob/cf31a6967aac76663b4cca023b5d760fd6eb5355/docs/exporter/prometheus/prometheus.rst |

There was a problem hiding this comment.
Thanks for that, I think this is good. The maintainers will be the next to look at this.
