I should've thought of this earlier, but I think ENV variables are only for
use within udev and, maybe, programs that use libudev. Assigning them
doesn't change anything in the kernel. "Writing udev rules" says:

    udev provides an ENV key for environment variables which can be used for
    both matching and assignment.

The evdev driver doesn work with udev, but instead queries kernel directly
using EVIOCGNAME ioctl.

Maybe there is a way to change that name, but I haven't found it.

You still have the option of disabling the mouse event device if you don't
use it.

Sincerely,
Nick
