Hello user, for an extra 10 dollars, would you like to guarantee that cosmic radiation never affects your computing experience, including having to reformat, reinstall, or otherwise reboot your phone/computer randomly when one day something just doesn't work anymore?
Was it an update? Was it cosmic radiation? Was it a bad capacitor? Who knows!
Why do you think so many problems are solved by rebooting? Sure 99 out of 100 might be software bugs, but the other 1 out of 100 is straight up cosmic radiation, and that 1 percent is growing more and more every year as software becomes more robust and bug free with better tooling.
So your hypothetical dialogue will sound more like a scam to a regular user. You're charging money to tackle a problem they don't have or see, only addressing a single one of the root causes that trigger that same result, and in the end you're not even completely fixing it, just reducing the already infinitesimal odds it happens.
It will become mainstream when manufacturers just decides to include it everywhere and not really give the user a choice. Apple is a prime candidate for a company with enough clout to afford this.
