Based on the knowledge sources provided, I can answer your question about Mixpanel version v2.52.0 and the utm_id parameter.According to the Mixpanel SDKs: Javascript documentation, the JavaScript library automatically adds UTM parameters to events fired from a page load, including utm_id. The documentation states: "The JavaScript library will automatically add any UTM parameters (utm_source, utm_campaign, utm_medium, utm_term, utm_content, utm_id, utm_source_platform, utm_campaign_id, utm_creative_format, utm_marketing_tactic) present on the page to events fired from that page load."This information suggests that utm_id is indeed registered as a super property in Mixpanel version v2.52.0, along with other UTM parameters.However, it's worth noting that the documentation also mentions a new option introduced in this version: "Note: UTM parameters are by default persisted as Super Properties. To disable this UTM persistence, use the SDK initialization option {stop_utm_persistence: true} (refer to our Release Notes in GitHub)."This means that while utm_id is registered as a super property by default, there is now an option to disable the persistence of UTM parameters as super properties in version v2.52.0.
