IMO this is asymmetric and right because the cost of keeping the packages on the system is much lower than the expected benefits they provide for the user.

IMO 365MiB over _years_ is not a lot at all the age of streaming 4K videos every day. Did you experience any improvement in the system's performance after removing the packages? I just checked the size of apt's package list cache on an Artful system as a comparison: ~$ du -sh /var/lib/apt/lists 367M /var/lib/apt/lists IMO saving a tiny amount of space and surprising people by removing more packages than before would hardly make the Ubuntu experience better. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1725861 Title: APT::AutoRemove::SuggestsImportant "false" should be the default Status in apt package in Ubuntu: Opinion Status in apt source package in Bionic: Opinion Bug description: After an upgrade to 17.10, I took a look at how much cruft I had accumulated on my system, and started marking various packages 'auto' which I know I don't care about keeping installed. apt autoremove didn't remove nearly as much stuff as I expected, and as I dug down into some of them I found that a number of them were being kept because other packages on the system have Suggests: referencing them.
