Testing for legacy Angular JS remainders on instance

As part of ServiceNow best practice, we want to set the glide.angular.legacy property to false to prevent older prepatched angular JS versions from being used and avoid attacks on vulnerabilities discovered in outdated Angular JS library versions, as described here:
https://www.servicenow.com/docs/bundle/yokohama-platform-security/page/administer/security-center/re...

Now I am wondering if there is a good way to search for outdated Angular JS libraries within the instance, besides going through records one by one.

Hopefully someone has already gone through this and can help me!
