This comment confuses me. It makes it sound like some authoritative figure came in and said, "Nix shall not support OS X because Apple is evil." But to my eye, this is not at all borne out by the thread.

There's one or two early comments which float the idea that Apple/Catalina's problematic technical change "may force us to drop support for macOS...". That prompted lots of -1's, and then there's a gigantic thread where people are trying to figure out how to adapt, and that's an on-going/non-trivial process.

Did I miss something? Is there actually a policy decision buried mid-thread that's hard to see?

In your comment, I pick up some fear/vulnerability. There's no reassuring voice to say, "macOS Catalina support will be fixed yesterday!" I share that sense of fear/vulnerability, but I think it's a natural trade-off when you sign up for free/open/transparent/community-driven software. For better and worse, you get to watch how the sausage is made in real-time.
