Okay, 2007 is pretty old, I can't fault them for not supporting these functions. However, this is a noticable trend with macOS. Their pace with modern Unix is severely behind, and I often get bug reports from macOS users lacking some API that's been available on open source Unicies for 5+ years. Plus, even if Linux in 2007 didn't support what you need, it's open source so backporting the required functionality is feasible, and impossible on macOS. MoltenVK is a good workaround, but open standards > workarounds.
