This is certainly true, but at the same time the device makers have a valid interest in making as many apps as possible be enabled without requiring a recompile. If it becomes known that device A supports 90% of the popular apps while device B only supports 70% of the same apps (until they get recompiled), the decision whether to put emulation in or not is more about maximizing revenue than about theoretical correctness.
