@Jarno I added update-manager based on my experience with (less experienced) users, who kept their system up-to-date by saying yes to everything regarding updates which popped up on their system.
They never touched apt or synaptic nor installed packages by themselves by other means.
I think removing newly unused packages would be a reasonable default for u-u and update-manager.
I agree that Remove-New-Unused-Dependencies=true is riskier than having it disabled but it still removes a subset of what Remove-Unused-Dependencies=true would thus Remove-Unused-Dependencies=true would be more risky.
Remove-New-Unused-Dependencies=true is needed to clean up old kernel packages filling up /boot (and the whole disk).
If update-manager defaults to that by default, too, the system won't break itself.
