Nobody is saying adaptive sync should only work with explicit target presentation times provided by the application. We're just arguing that target presentation time as a mechanism is superior to target refresh rate, both for video and game use cases. It also trivially allows emulating "as early as possible" (target presentation time = 0) and "fixed refresh rate" (target presentation time = start + i * target frame duration) behaviour, even transparently for the application.
