Question about those new push-in wire connectors

I had a call last week in a 90s house where a light fixture kept flickering. Opened the box and found a push-in connector on the hot leg that was just warm to the touch, not even hot. I've always used wire nuts, thought these were fine for small stuff. Pulled the wire out and the contact spring inside was all black and crusty. I replaced it with a Wago 221 lever nut and the flicker stopped. Anyone else run into these failing under normal load?

Yeah, I found a melted one just last month behind a switch plate.
