I think that's an issue with how Microsoft has screwed up redone the documentation for SQL Server. They have some things specific to 2017 that are listed as applies to 2016 and later. They have a ton of documents on things where it's listed as starting with 2008 even if it was introduced in earlier versions. It's become incredibly difficult to figure out what applies to what version anymore. They took one of the stronger points of the product and turned it into a weakness. I'm waiting for clippy to pop up to help me with backups and restores. And totally screw it up.
