Supposedly they are a good idea. With a standard trigger the pins are designed to rotate. With a cassette trigger they don’t rotate. So they rely on tension screws. But that’s not the greatest idea. So the thought behind em is lighter tension, and use the anti walk pins to ensure pins stay in place.
This is only what I’ve read. I haven’t seen any further proof that this is the case.
Good read below on why anti rotation pins suck.
