Actually, there is often a very big difference between whether the failure occurs at the requirements level or at the implementation. The difference is that the end-user may have access to the requirements document (he/she may have helped to develop it) and can check it against his actual requirements (assuming he knows what they are!). But even if the end user has access to the implementation detail, he is unlikely to understand it, much less be able to determine whether it is correct.

Now of course you might be talking about higher-level requirements documents, in which case you have something of a point - but when a malfunction occurs, whether the bug is in the code written to implement the requirements document or in the requirements document itself is a distinction of little import to the end-user with the problem; all it affects is whom to blame, and that much only at levels at which there is a distinction between the sources of the two.
As Dick Francis put it in another context: It does not matter to a bettor whether the jockey fell of the horse, or the horse fell and took the jockey down with him. The bettor loses either way. Still, it makes a world of difference to the jockey.
