Catch on ledges?

I was exploring Upper Fortus, and though I'm normally able to navigate narrow spaces well, my game was experiencing lag, and because the timing of the lag with my movement wasn't right, I walked off a bridge to my death.

This reminded me of how ledges were handled in U8, where whenever you came close to falling, there was a catch before the game let you fall.

Now, I don't want any hand holding in this regard, and I think enemies should be able to push you off bridges, you should be able to intentionally fall off, and you should fall off if you aren't careful. But it also sometimes seems way too easy to fall off -- especially if your FPS is low.

So, I just wanted to bring up the suggestion that there might be some solution that could bridge the difference; making it possible for you to fall or be knocked off, but still reducing how easy it is to do it by accident.
