In the worst case (they change the interface spec and no one else produces old modules, or the company folds entirely) it's not any less maintainable than any other laptop on the market today. I think most laptops still allow storage and battery upgrades/replacement; RAM is questionable (some being soldered on the motherboard); and anything else basically means replacing the whole device.
