Automation at startup: 'Overridden from config initial_state'

several of my automations are turned off by default using

initial_state: 'off'

most of these are older automations no longer in use, but kept for reference, and testing purposes. Some of them need to be off at startup, but are turned_on during operation.

Using debug mode for logging scripts and automations, I now see this in the log:

DEBUG (MainThread) [homeassistant.components.automation] Automation automation.call_service_event_switch initial state False overridden from config initial_state

for these automations.

This seems a bit remarkable since the initial_state is still an official option for automation, see https://www.home-assistant.io/integrations/automation/

why then would it be overridden from config initial_state (assuming that is the restore function reading the last state the automation was in, and restoring that)?

thanks for having a look

still unanswered, and still happening… anyone with a hint?
