Perhaps a security issue only could be fixed by an upgrade + generating new keys and/or passwords. Beyond that an upgrade shouldn't happen, while DSP load is critical and you e.g. are recording something important, let alone that an upgrade always could cause an issue, so it's wise not to update as long as you use the computer for audio work, that doesn't allow an interruption. Users should learn to maintain a computer in the same way they maintain their cars. They don't change oil while driving.
