unattended-upgrades should not be allowed to autoremove. Doing
so always ends up with surprises, unless you have pre-tested
everything and keep your own apt repo a day or two behind
Debian's.

Unattended-Upgrade::Remove-Unused-Dependencies "false";
Unattended-Upgrade::Remove-New-Unused-Dependencies "false";

However, 
Unattended-Upgrade::Remove-Unused-Kernel-Packages
is usually safe, unless you have very specific reasons to keep
multiple old kernels around.
