apt rejects packages with bad crypto if you ended up updating/upgrading
from a bad/compromised archive. If an attack like this was successful
(highly doubtful) whether we're automatically updating or manually
updating, let's just say we're all screwed. :(

If you've manually edited a configuration file and apt assumes 'yes' and replaces it with the new default configuration file, things can break. Say, for example, we're talking about grub and a /boot/grub/menu.lst. If you've manually edited to include paramaters on the boot line and the file is automatically overwritten, conceivably, you could end up with a non-bootable system.

Completely agree with the above three points of yours. The last one is
actually the most insightful and perhaps the most important.

BTW, is something the matter with line breaks in the application you are
using to post here? Each of your paras is one long line in my reader :(
