This is my point. It will almost always be ignored...unless the caller really needs to know the information. The logger will fail silently, only an object will be returned (no exception thrown) and the caller can safely ignore it.

You cannot necessarily know if there has been a problem with a logging call by the time the logging call returns. That logging call could be asynchronous.
