Lens extenders and extension tubes do not have integrated motors. They are merely pass through interconnects to lenses that do. While I understand the intent in including these devices in the list it makes the heading incorrect.
Gerold's list is more correct in that it only includes lenses with motors. It is also a living list with new lenses being added all the time. Adding the comment ... to be continued ... affirms that.
