I don't think it was a case of it "happening to" people, as in HR took them out back and put a bullet in their head... just social pressure. Internal elitism, perf comments, slowly chipping away at you, maybe even toss you on a PIP. Until you throw up your hands and leave. After all, other employers would be more than happy to have you.

But yes, it was officially dropped. I stayed as L4 for 10 years. But when I transferred teams I occasionally got ... attitude.

Thing is, if you go from L4->L5 (or L5->L6) based on performance you're expected to stay or improve on that performance once you're at L5, and if you don't, you'll get up with Needs Improvement, and there's no going back to L4.
