I've added the following text to the noble release notes about the default config file; let me know if this matches your understanding of the changes. Regarding the service file changes, I see the churn you mention however I'm unclear if this affects user experience so haven't mentioned it; please feel free to add anything you think should be said, or let me know.
The default configuration (/etc/default/exim4) generated for fresh installations differs from past practices, and a number of settings (QFLAGS, QUEUEINTERVAL, COMMONOPTIONS, QUEUERUNNEROPTIONS and SMTPLISTENEROPTIONS) have been replaced. As well, the update-exim4defaults script is no longer used for setting run parameters for the Exim daemon; users are encouraged to edit /etc/default/exim4 directly to customize.
Thanks for the review Andreas.
