This could have resulted in a rejected take-off on a very dodgy runway surface with a potentially catastrophic over-run. It would probably not have been pretty.
If the de-ice operative is unaware/has forgotten about not spraying fluid on certain areas of aircraft, then some retraining is required - report it as soon as possible.
Why do you want to retrain the poor guy? If all the fuselage is covered with deicing fluid on take off run due to the wind it will run back? APU intake doors are opened so it sucked a bit.
