I don't get why they aren't retiring notepad instead. WordPad is just as light and fast while having more features.
Not that I really care, I never touch either ever since MS basically stopped developing them 25 years ago. Notepad++, atom, etc, there are so many superb lightweight editors out there.
It's not very useful. But, I can start a program from an app which is a lot easier than understanding all the little logos on the unit. Plus I have more flexibility to tweak it, like be faster or gentler or schedule it to cheaper electricity hours all much more easily and intuitively than in the panel.
Also timer, remote start, and letting me know when it's done are something I might use once in a blue moon.
Can I live without it, hell yes, but is it a totally useless gimmick... Well 50/50.
