IMU needs to be calibrated and placed in certain way. To calibrate it it needs to be rotated in many ways. Recalibration might be needed periodically. Due to that it makes sense to have IMU in a small waterproof box separately connected via i2c.
I think no need to put IMU inside hard mounted to this HAT.
That separate small box with IMU needs to be easily dismountable.
