This is not related to the Content-Security-Policy (CSP) header.
This is afaik not related to an Analytics service or feature. The intake-analytics.wikimedia.org is implicated by reference only as it naturally has to be listed for permission policies like this, but there is nothing the EventBus (intake-analytics) service or its configuration can improve to avoid this.
The interest-cohort header was added as part of T279804. Browsers that don't support it emit a warning about this, which does not affect any functionality and does not represent a production error. As per the aforementioned this, this header is implemented by the Traffic team and conceptually supported by the Security Team.
I'm rephrasing this as low prio clean up to remove the now obsolete header as the FLoC experiment has been concluded by Google afaik.
