Huh? My comment explains it doesn't ruin the feel of the keyboard, which was my pleasant surprise. Typing is basically exactly the same experience. And at least on my Late 2016 MBP there is zero impression on the screen. (I can't speak for other models.)

And the issue is debris with the new keyboards. I haven't heard anyone complaining about a failing mechanism. Everyone's complaining about dust and debris getting into the mechanism which prevents or multiplies keypresses.
