macOS is still certified POSIX UNIX

EDIT: maybe not anymore, Sequoia isn't listed yet, https://www.opengroup.org/openbrand/register/xy.htm

Regardless, even if they renew the certification, they aren't obliged to expose in the classical POSIX APIs more than what the certification requires in features, or happens to be optional, implementation defined.

As anyone that has painfully tried to write POSIX portable code across big iron UNIX is aware of.

getaddrinfo() is part of POSIX, so it would be necessary to expose it:

* https://pubs.opengroup.org/onlinepubs/9699969599/functions/g... (2004)

* https://pubs.opengroup.org/onlinepubs/9699919799/functions/g... (2017)

* https://pubs.opengroup.org/onlinepubs/9799919799/functions/g... (2024)

And it is exposed, the code still compiles if one uses it, it just doesn't get additional nice macOS networking features that aren't explicilty required for UNIX certification.

Where does it say DNS encryption is required?
