Basically what it says in the title.
Is it expected that /var/db/auth.db is recreated when updating to a newer macOS major version?
This effectively removes the installed authorization plug-ins from the login flow, decreasing the intended security. And it's not a good end-user experience either to have to reinstall the plugin after updating - nothing such can be noticed with regular applications.

Yep. That’s how the system currently works.
It sounds like you’d like to see that change, in which case I encourage you to file a bug report explaining how this issue impacts your product.
Please post your bug number, just for the record.
Share and Enjoy
