There is an option to disable Check In of Design files through Vault Client and avoid losing references with other files. It would be nice to have also option to block opening CAD files via Vault Client (as per the recommendation to always open CAD files using the respective CAD Vault add-in). My idea is to add another option under Vault settings (like on the screenshot below) to block it from admin level.
Example scenario when it can help to avoid broken references - https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/When-using-Autodes...
