It is a bit of a power user feature, but it's important to two groups of power users in particular: reviewers and developers. These are two groups that it pays to help. Apple certainly doesn't make third-party developers its first priority, but they are decent at helping developers when it doesn't get in the way of Apple's desired user experience. One way they do this is by providing good developer tools and workflows.
