The problem that we're facing today is that all of the signals are getting faster and that this approach to protecting internal components is now starting to interfere with those signals. This leads us to the need for more intelligently designed connectors as well as some intelligence on the part of those standardization committees who are responsible for adopting the connectors (if we are indeed faced with a ruling that states we must discharge to the exposed pins in a connector).
