Yes, but it's not like they don't warn people. From the Docker docs:
"This backend is pretty fast, however btrfs is still maturing and is not considered production ready for heavy write loads. Mounting /var/lib/docker on a different filesystem than the rest of your system is recommended in order to limit the impact of filesystem corruption. You would also want to mount the volume directory /var/lib/docker/vfs/ on a standard XFS or EXT4 filesystem to ensure container data is protected."
