I'm not sure I understand the question - other implementations should
follow whatever is decided for the library interface, right?=20

I'm really not arguing either way, in fact I like the change, but
perhaps we should think hard before breaking code.  I haven't heard
anyone else comment so far on whether they like/dislike the current
Exception interface... anyone?
