  # This is dangerous! However, plugins need to be able to run whatever they want.
  # Only admins can install plugins and they need to be vetted for content.
  # NOTE: In OpenC3 EE each microservice gets its own container so the potential
  # footprint is much smaller. In OpenSource OpenC3 you're in the same container
  # as all the other plugins.
