That's exactly it. I've used btrfs in production since Ubuntu 10.04, at scale since 12.04, and had nothing but great experiences with it - especially with the seed volume functionality, which allowed me to build the foundation for a major container-as-a-service platform before Docker was a thing. btrfs never lost our data, but I've also seen way too many btrfs kernel panics that were clearly related to insufficiently mature filesystem code, and I can understand people who did lose data, got burned and never want to trust btrfs again.
