I agree, it probably would be best to avoid disabling that feature if it can be avoided.

Regarding the mouse_ignore list: It looks like the device ID (at least for my trackpad) is already in the hid_mouse_ignore_list (my trackpad has an ID of 05ac:0252 which corresponds to USB_DEVICE_ID_APPLE_WELLSPRING5A_ANSI). If my understanding of what's happening is correct, I think the mouse_ignore list might only be used by the usbhid module, and not by the usbmouse module that we're having a conflict with. I looked through <https://github.com/torvalds/linux/blob/master/drivers/hid/usbhid/hid-core.c> (for the regular usbhid module), and that looks to have code to handle device quirks, including ignoring the device, whereas <https://github.com/torvalds/linux/blob/master/drivers/hid/usbhid/usbmouse.c> (for usbmouse) looks like it doesn't have any of that. I guess that would explain why a lot of other distros blacklist the usbmouse module by default. That being said, I've never touched kernel or driver code, so I could definitely be overlooking something.

If creating a void docs page for this turns out to be the best solution, I could try working on a macbook page like the one @ericonr linked. However, since I have a different model of macbook than the original author of that PR, I've only experienced the trackpad issue and none of the other issues mentioned there.
