It easily could break an existing Dashboard widget. Upcoming versions of
Dashboard load multiple widgets in a single process, and if a widget loaded a
plug-in that made this call, then it could break plug-ins in other widgets.

We don't know that this issue is limited to Dashboard. It's true that the first
trouble we found was in a Dashboard widget.

Could be -- I'm not sure how to get to the plug-in from inside the bindings
code efficiently, but perhaps it could be done. Sounds challenging to me.
