Yes and no. They've taken down the documentation, but there's still a number of (non-GUI, non-kernel) Carbon APIs that are still not deprecated (as of 10.11, at least), and still allowed in the Mac App Store.

I'm using AHGotoPage() because NSHelpManager has no equivalent and nobody has been able to explain to me how to make that class do a similar task reliably. (In hindsight, AppleHelp is such a disaster that I should have just avoided it entirely, as almost every other app does.) MAS reviewers have given me grief over many things my app does, but never any Carbon calls.

The last time I saw any Carbon APIs deprecated was 10.8, I think (6 years ago).
