Symmetric multi worker processing #1386 doesn't permit to execute any plugins and configurations in just one process.
But there are requirements and feature requests for such use cases. For example, executing plugins for monitoring (should be unique in a server).

<label @traffic> # this section works on all workers too
<worker 0> # this section works only on first worker process
