Apple never really maintained CUPS. They hired the author, Michael Sweet, and he pretty much served as the printing team. He left Apple a couple years ago, and basically stalled their printing department.
He’s recently become head of the Printer Working Group, and they’re all pushing IPP Everywhere towards greater adoption. It’s a laudable effort.
After he left, all his cups commits to Apple's public CUPS repo stopped[1] and his work continued in the OpenPrinting fork of CUPS[2]. Interestingly though, it seems he resumed committing to the Apple repo in March. I'm glad CUPS on macOS isn't going to be left behind, but I'm curious what happened there.
