Yeah, I love the original name, but it would have been problematic potentially with copyright. As for breaking the format, sometimes there's good reasons for it. I can tell you that it really flies though, when compared to Borg/Vorta. I can't tell if the speed improvements are from the Rust front end or the back end format changes, but it's a lot faster than Vorta/Borg and certainly way faster than Kopia on restore.
