Simply rebuilding and resubmitting the app with a new version of Xcode will yield a significantly different binary artifact today than a few years ago. It isn't necessarily about API level, it could be (from time to time) about going from arm32 to arm64, to adding better-optimized builds for new microarchitectures, getting bitcode that's recompiled by Apple to support app thinning. Apple may deprecate or remove APIs from time to time that should also be addressed. That there wasn't necessarily, specifically, a change this time doesn't mean that this program isn't about supporting that over time. It's much easier to make such changes if developers are in the habit of periodically making updates vs. being told to make a breaking update out of the blue.
