I wouldn't be surprised if there are cases where it would make sense for the utility to operate and sell the additional reliability, rather than the customer DIYing it, whether because there are grid topology things they can do to get the result more effectively or just because they have greater experience with alarming AC gear; but that would be a tier above the standard offering, not a concession that it's reasonable to run the entire grid at the level of the worst-case customers.
You could get into the same argument about water. Hospitals and precision chemistry applications often have fairly elaborate onsite setups to provide sterile or ultra low ion water for their particular requirements because that's not the standard to which utility water is normally held. In theory you could shuffle around ownership and responsibility for the additional processing steps, and in some cases it might even make sense; but it's not terribly compelling to run the entire water system as though it is being piped into a burn ward or a chip fab; and, at least in agricultural areas, there's often another tier below the 'standard' for non-potable irrigation where you can worry less about microbe counts and whether there's matching sewer capacity because it's just getting sprayed on fields.
