Well, actually five... You left out the 17-120, 25-250 and 50-1000 Cine Servo's.Except Canon already has two cinema zoom lenses that have AF, the 18-80mm t4.4 (https://www.bhphotovideo.com/c/prod..._e_18_80mm_t4_4_compact_servo.html?ap=y&smp=y) and the 70-200mm. You could argue that they are hybrid lenses, but they are called "cinema zoom lenses."
I have't tried it on my 25-250(for several reasons), but I have put my 17-120 on a 300/II and activated the AF and it is kind of crazy watching a lens like that being driven by AF.
