I dunno what vehicle you use, but on mine, I can easily switch between profiles. So if I were to have a profile where I set the trim to apply throttle during neutral, I'd also set an identical trim where neutral was true. So, right before the start of the race, I'd switch to the profile with the "powered" neutral, but otherwise leave it under true neutral, as I would suspect its HORRIBLE for the ESC (as well as the motor and battery) to have the truck always under some sort of throttle, no matter how little).

However, if you do this only when you are lapping, I can see no real issue - just be sure to hold some level of brake unless you are actually driving, and it should be fine.
