Nobody is obligating app developers to support umpteen versions of iOS. There are 2 possibilities: 1. Users who want to stay on old versions without access to the newer app store stay. This happens all the time with people who have old iPads they want to hand off to their kids/grandparents/whatever. 2. Apple stops pretending that there are enough new features every year to merit a major version of iOS, and gates updates for newer packages to only users of the newest phone. They already have the capability to do this for iPads, iPhone X, and others.
