Hi Kevin, Nope - we haven't removed support for the "full" backup format yet. IMO there's no reason for a user interested in collection-level backups to use the "full" format, so it should be safe to remove the "incremental" parameter from the create-backup API.
In terms of removing the other code associated with the "full" format, that might be a bit harder to remove, since it's also used by the INSTALLSHARDDATA" API [1]. (This API didn't exist at the time SIP-12 was written.). I'd love to see a lot of the code for the "full" format removed, but as a first step we'd probably have to figure out what the impact would be on INSTALLSHARDDATA. Happy to collaborate on it if you're interested in pursuing, let me know!
