> these are shared Nix configurations between macOS, Linux, and WSL on Windows
This is the "killer app" of Nix for some people. I've got a lot of machines, spread out between a variety of usecases. With Nix, I can have individual module files for my desktop apps, my gaming software and my terminal configuration, then link them into the various machines that need it. Once it's fully set up, you can essentially manage the environment of dozens of different machines in a single Git repo.
Nix will frustrate people because it doesn't offer a lot of imperative or immediate solutions to things. If you can handle the learning curve though, you'll be hard-pressed to find a more comprehensive package management solution on any OS.
Despite how the learning curve keeps the Nix community relatively small (it's grown a lot since 2021 actually) nixpkgs has assimilated like 90% of OSS. Learning Nix is hard, but once you know enough Nix to be productive it's a huge enabler.
