I have very little idea about what's required for a safety assessor, sorry. Will this have an impact on what tools are allowed to be used when working with certain parts of Xen?

Maybe what you want to do is create a specific container in the Gitlab CI that has the specific tools versions you care about from a safety certify angle. Regards, Roger.
