No longer maintained?

According to mjcf.py:

UserWarning: Brax System, piplines and environments are not actively being maintained. Please see MJX for a well maintained JAX-based physics engine: https://github.com/google-deepmind/mujoco/tree/main/mjx. For a host of environments that use MJX, see: https://github.com/google-deepmind/mujoco_playground.

This message is confusing. Is Brax no longer being maintained? If so then the README should state and explain this status. I was under the impression that MJX was going to be added as a back-end to Brax.

MJX was added as a backend in brax, but as of now, only the brax/training code is actively being used. We'll update the README
