This is very different from a sudoers file though. Apple has full control of how those things are configured, so they could easily migrate the values if they want, for example.

The fact that they doesn't shows either a malice from them, or at least very sloppy engineering/product management.

Because this kinda of attitude is really bad, and if it was a product from any other company (like Google) I am sure that people would say that this is proposital.
