I rebuilt my cluster this morning so I don't have the logs anymore... but
what I noticed is that this callback gets called multiple times (once per
container belonging to the app), while I only remember the stop callback being
called when the application actually stops. So it didn't seem like the behavior
was as symmetric as one would expect.
But the secret manager also prints an info message on unregistration, so I
guess the important things are still logged even if these two messages are
removed.
