I initially had that internal reaction too, but then realized that the value in CoreOS was the updates. If they're specifically going to stop that, at this point it's like any other never gets updates OS (sure the readonly file system still helps tremendously) - so yes, people should get off ASAP. But the September date ensures that anyone that wants to fork and provide updates some other way, can definitely find the time to do that.
