Honestly, the mechanical production time and maintenance isn’t really much more then a standard custom skid steer chassis in today’s FRC. This was more true 5 years ago. With 3D printing and the amount of COTS solutions available (AndyMark, Swerve Drive Specialties, WCP) mechanically it is not that complicated or difficult to pull off. It isn’t even much heavier then a skid steer.
The biggest thing really is programming and then just driver familiarity. For these reasons I would still suggest taking time in the offseason to build one and develop the code for it, and to give drivers a chance to get used to it. That said, imo this should be done for any drive train really, even skid steer.
