How many of them actually work though? If you end up having to go fix upstream packages then having a tool manage your environment is not useful since you still have to understand the domain.

With Nix I usually ended up in a situation where I had to both figure out how to configure my environment _and_ fix the upstream Nix packages. At that point it’s just easier to stick to Homebrew and some custom shell scripts.
