thanks for reporting this @jackwilsdon, we added this into our backlog though it might not receive enough priority to be released in the short-term. Please consider using other open-source alternatives such as the prometheusreceiver in the OpenTelemetry collector to scrape metrics in non-orchestrated environments or the Prometheus remote-write integration. For k8s, we'll recommend New Relic's Prometheus Agent.
