What's weird is that a decade ago, bottoming out was a concern in the mechanical keyboard community. A selling point of mechanical keyboards was that you didn't have to bottom out; that's required on a membrane keyboard by their nature. O-rings were a very common way for people to fix bottoming out without having to learn to stop their fingers before reaching the end of the key travel (it was also a way to make the keyboards quieter by avoiding the clack).
