I believe that the provision of access to the basic parts of the 
exception, as described here, is not unreasonable. Its not one I 
consider essential however.

If it can be achieved without over-complicating the exception then fine, 
however I suspect that to achieve the goal will require many more 
classes and methods than this actually justifies. This is a case for KISS.
