Can't we detect and avoid this more easily?

Can't we just treat 'failure' mode as always defaulting to legacy
sendmail? And properly deprecate the setting, showing a warning/info
that new notification system is not used if set to 'failure' for both
CLI and UI. And maybe not even allow setting it for new jobs/manual backups?
