Ack, got it and agree that the distinction is likely helpful: the
supervisor node implements the low-level "dirty work" of stopping
processes and can ensure shutdown of its entire process tree if it
really has to, but the client can carry out shutdown logic with a
higher-level of insight into directing a shutdown process (possibly
across many hosts) in orderly fashion.
Also, based on "naming" feedback: plan to use `zeekc`.
