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.
