Not true; UX designers typically are responsible for advocating for a robust, intuitive experience for users. The fact that kernel updates don’t have a user interface doesn’t make them exempt from asking the simple question: how will this affect users? And the subsequent question: is there a chance that deploying this eviscerates the user experience?

Granted, a company that isn’t focused on the user experience as much as it is on other things might not prioritise this as much in the first place.
