The `InsightsRuntimeExtractor` feature gate still exists: https://github.com/openshift/api/blob/41708f6123394c18afbb4bef1bac526f46960769/features/features.go#L119, however in 4.19+ the feature is GA and the feature gate does not seem to be doing anything, as the code that was managing this enablement was removed here: https://github.com/openshift/insights-operator/pull/1081/files#diff-ae229fbd6b01ded5fab0e20b063bd9ce498c0f5c0ece1202648e2f94a2ece081L239

In the github comments there were talks about removing the feature gate here: https://github.com/openshift/insights-operator/pull/1081#issuecomment-2796559574 but it does not seem to have occurred.
