Yeah, except it exists since 2015, and while it is great that macOS is getting them, which I am perfectly aware of, it isn't what I meant as "Sadly it is still years away on ARM and x86, Linux and BSD systems.", because it isn't neither a Linux system, nor a regular BSD.

Apple OSes don't count for the BSD group I was talking about, because they only took whatever NeXT felt like back at the time, and there have been very few updates other than those required for UNIX certification.

While on Linux, you might be tempted to point out Android, however NDK alone hardly makes it a GNU/Linux system.
