Why is the ros_skid_steer_drive not publishing coordinate transformations?

[CanaanHeart]

When I configured the controller for the four-wheel differential car, I found that the car's wheels did not rotate in rviz.
When looking at the source code, I found that there is no implemented function publishWheelTF() and publishWheelJointState in ros_skid_steer_drive.
Implemented these two functions in ros_diff_drive, so when I use this controller for the rear wheel, the wheel turns normally in rviz. I would like to ask why coordinate transformation is not implemented in skid_steer_drive, or in other words, does it have any impact on my gazebo navigation simulation?
