In over 25 years of using grease on threads I've never experienced any of the problems you have had. Never had an aluminum headset "drift" on a steerer tube (that's what the locknut is for) and never had a Nuovo Record or any other derailleur lose its adjustment. Campagnolo's derailleurs have used springs to keep the screws secure in their place and I have never had one back out.
Oil or grease keeps the exposed BB axle from rusting ;)
