And yet Xcode is very successful and well-liked, or at least if it's hated, it's not for the flaw you found.

Doubtless many, many other apps have also made that same mistake, yet I highly doubt it has made the difference between success and failure for even a single one of them.

All of those OS features were introduced to help people, because people wanted them, some even needed them. I don't think we live in a worse world for having them, and I believe that dealing with features like those would actually be even harder in a world without the Web.
