For anyone looking for the core issue it is https://www.drupal.org/project/drupal/issues/3304450 ✨ Implement SRI for aggregated assets Needs work
Since Drupal 10.2 added the content-length header ( https://www.drupal.org/node/3298551 → ), automatic injection of the RUM JS by the New Relic APM PHP agent is disabled, see https://docs.newrelic.com/docs/apm/agents/php-agent/features/browser-mon....
Auto-instrumentation does not work when the HTTP header field Content-Length is set. To use browser monitoring in this situation, disable auto-instrumentation and manually insert the JavaScript header and footer into your templates.
This may mean a solution like this becomes the next most sensible way to add the RUM JS.
I've pushed a 8.x-1.0 release with D10 support, thanks for the contributions folks! Bear in mind this was my first merge with Gitlab so I've probably done something wrong in the process somewhere... ideally we would switch to semver but I didn't want to mess things up too much.
