If we talk about physical replication, then with the same success
restore_command could be (and more important, it should be) used on a
standby. And the main question here is why standby wasn't
properly configured?

However, with logical replication it is a different story, and it would be
really great if restore_command is used when WAL's are missing to fetch it.
