they didn't drop it, it's still the default data format.

This is the best explanation I've found:

According to them, if you sync to dropbox or an external folder and use their default external file format for it, you might expose metadata, otherwise, you're fine.

“Default data format” is not correct. Data / Backup stores in a SQLite database locally. OPVault in iCloud, Agile Keychain for Dropbox / Folder Sync.
