The problem is that most of the time, errors are not to be handled but only bubbled up. I've also seen it in Java with checked exceptions: the more explicit error handling is, the more developers feel they should somehow try to do _something_ with the error when the correct thing to do would actually be to fail in the most straightforward manner. The resulting code is often much heavier than necessary because of this and the stacktraces also get polluted by overwrapping.
