Or, perhaps buyers, now they can get a low-maintenance drive train, should demand vehicles that don't rust. Obviously, suppliers will not like that, because vehicles with a life-span of several decades are not good for business, but if customers insist, they are going to have to supply them.

That is a possibility, but I think there are some likely problems. First cost is one, as school budgets are usually pretty tight already. Evolving standards are another. No point buying a 50 year school bus if standards require getting a new one every dozen years. Changing demographics yet another in some places, where the school population is hard to predict. It's hard for people to plan that far ahead.
The article I saw referenced California and Maryland, so chances are good that rust will be of little consequence, and as long as the buses meet standards, and withstand normal wear and tear, I expect they'll serve well. And if the running costs are as much lower as I suspect they might be, the lifespan will be a lagniappe anyway.
