The key point is that minimum support is not the same as a great experience on every older device. A service may technically run on a supported operating system and still feel slower, less reliable, or more limited than it does on current hardware.
The safest reading of a support statement is this: if your device is below the listed requirement, do not count on it. If it meets the requirement, you are in the normal support window, but it still makes sense to treat the official support page as the final source before buying new hardware or locking yourself into a plan.
