It is possible to control the temperature of the MPU6xxx in the Bebop2 and Disco through resistors powered by PWM_6. Code mostly taken from Ardupilot Seems this does not make a big difference even if flying in cold conditions but does rather improve things than do harm. MPU temperature will go to about +15 deg C in a Bebop2 at 0 deg C ambient temperature. Having the gyro/accel calibrated at just below +50 deg C after running the original Parrot software creates a 30+ deg C change.
