In my experience individual chokes in series with each of the paralleled FET gates in the form of a ferrite bead or 5-10uH choke often helps quench HF oscillations - these can be in the MHz range. For sure these little beads can do wonders. I trialed one bead only once and saw the rise time of the gate voltage become way too slow. no numbers, sorry, it's from the dim dark corners of the memory. But certainly, if I took the time to specify and source reasonable value ferrite beads I think we could remove some of the circus of oscillations wronger than a phone book full of wrong phone numbers
