In my experience with a variety of switches and microcontrollers this actually isn't too big of a deal as it used to be. It is worth testing out, but I think it's worth testing before investing a lot of hardware/software development on it. Adding some resistance or a simple RC low-pass filter can help, and also many microcontrollers come with basic anti-bounce inputs. As other posters said another easy effective strategy is to just ignore inputs after the initial transition. You can do this and still pick up long presses too if you need to!
