I don't know that there's any policy to disable tracing on Android. The
Android framework in fact has generally been instrumented by Google
itself to output trace info into trace_marker. And the systrace/atrace
tools made available to app developers need to get access to this
tracing info. So, if Android had tracing disabled, systrace/atrace
wouldn't work.
