EDIT: I read more of the USB guide to understand exactly what that is doing. If my understanding is correct, the reason for routing USB2 devices to EHCI is to get around the 15-port limit on 10.11. My machine only has 7 USB devices: 3 USB-A ports, BT, webcam, touchscreen, and SD-card reader (disabled in my custom port injector). If my understanding is correct, then my machine should function just fine if I completely disable EHCI.
Yes, assuming the touchscreen is not directly wired to EHCI.
Note that your 7 USB devices actually use 10 ports (3*2+1+1+1+1)
