This should be done to increase compatibility with different action the robot can do.
For example a kick also needs to publish a support foot but it would not be logical to publish on /walk_support_state. It is also not practical to add a new subscriber to humanoid_base_footprint for every other action.
currently the base_footprint listens to walk and kick and works. I will close this issue for now, since I don't expect any further support sttes in the near futur
