multiple times under different names with different ``kwargs`` (for
example, two ``JavaCoordinator`` instances pinned to different JDK
versions).

+ An entry may also carry an optional ``extra`` object for additional
+ information associated with the coordinator that the coordinator itself
+ does not receive; other components read it as needed. For example,
+ KubernetesExecutor reads ``extra.pod_template_file`` to launch a
queue's
+ worker pod from a specific pod template, and
+ ``extra.worker_container_repository`` + ``extra.worker_container_tag``
to
