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.
