IIRC, normal thermal compound is electrically insulating and if they are using the tab of the FET as one of the conductors, then it would be like adding resistance.
Could also be related to the environment that the controller is meant to operate. Maybe the TIM stuff back then had some issues with certain temps or humidity levels making it more of a thermal hindrance than help.
