Problems due to apt operations should be pretty rare, but even uncommon events can be worth de-risking. The value in providing this kind of feature is: * For expert users who have hosed a system -- particularly if it happens to be a production host -- there's an immediate sense of relief and ability to rollback safely, confidently and quickly. * For less-experienced users who run into problems, there is a convenient and straightforward way for their technical support to explain to them how they can restore their system to a previous state. Since hosts and their installed packages have varying hardware and configuration states and update/maintenance schedules, incompatibilities and breaking changes are likely to occur occasionally and that's where snapshots can help.
