And they won't want to change over until things are finished. It's a bit of a chicken-and-egg thing. I figured that doing this on a branch first and then outlining how to change the front-ends and/or create an Auto-upgrade tool would be the best course of action.

There should be no breakage for existing code until the frontends switch to generating the new EH stuff.  This can also be done under a flag in clang for example.
