> Producing output from another thread will break the assumption that users who use this library may have where they don't need synchronization since methods like startBundle/finishBundle/processElement are all meant to be [accessed from one thread|https://beam.apache.org/documentation/programming-guide/#user-code-thread-compatibility] and will also break similar assumptions in the system (for example counters/monitoring rely on a thread local being set to pass a context object around).
