Why don't you setup recovery_end_command parameter? The trigger_file is
important in some (legacy) environments and that is using an external
tool to handle the service initialization.
It seems to me it is an opportunity to improve trigger_file description
(informing a way to cleanup the file created) than to suggest it is not
useful.
