There are plentiful reports of Magento releasing new versions and patches that are "buggy". When new versions come out, many issues can arise for users. Since most Magento users have numerous plugins from different third parties and use multiple developers, it can cause compatibility problems, security problems, and errors when Magento rolls out upgrades. It can be tricky to fix the bugs properly when you're dealing with code written by developers working for different third parties, and there will be no single "source of truth" manual for knowing what needs to be done to fix the bugs. It would also be your responsibility (or your designated third party's responsibility) to install the upgrades.
