They can work, but they are much less tolerant of the robot from not being flat and lumps in the carpet, etc. Your driver will naturally compensate for these things, but the sensor just measures what's really happening.

Also note that the encoder is measuring the wheel rotations, which for mecanum wheels does not directly translate into distance = circumference * rotations. You will have to invert the mecanum control equations to make sense of the 4 wheel position channels.
