My original post was an objection to the implied intent on the part of compiler writers. An electrical socket does not have intent, it's just a hazard that also happens to provide enormous benefits to our lifestyles.

I think it's a perfect analogy to undefined behaviour in C: enormous benefits but also a hazard to be wary of. A lot of people don't understand the benefits, they just see the hazard. Throughout this discussion I've been trying to clarify that, with perhaps limited success.
