Short answer: no.
Long answer: Please! The more people exercising the code, the more bugs will be revealed, and the more confident the developers can be. But you will have to be ready for some performance regressions and data loss danger. For the brave.

Performance is still pretty bad, especially when deleting many small files. It can take minutes with BTRFS, while EXT4 does it almost instantly in comparison.
