We never promise that the messages won't change (they are not part of the API), so that part isn't a problem.  We do try to be backward compatible there when it comes to args beyond the message text.  I don't think unpickleability is an issue; at least there isn't any discussion of it in PEP 3161, and I don't remember any around the implementation.

I think this is fine.  I don't think we should worry about someone who is actually using rawval/rest pulled out of the exception args.  You could put a porting note in What's New, but my guess is that the chances of anyone being inconvenienced by this are pretty near to zero.
