Building those applications consistently and reliably, e.g. being able to hop on a random Linux box and be able to build and deploy an application without thinking about where to fetch copies of all the dependencies. Nix’s raison d’etre is really to make developer lives easier, IMO. I don’t use Nix, but I’ve played with other Linux package managers enough to understand the desire for something better, and something t…
"build and deploy" are two entirely different tasks. Both the macOS .app design, and various ad-hoc Linux packaging strategies deal with the deployment step in a relatively trivial, extremely non-invasive way. The build step is something else entirely, and while I can imagine that for some projects what Nix offers has much value, for others the problem is solved by a permanently deployed build stack (or stacks) whose…
> a permanently deployed build stack (or stacks)
with a consistently deployable build stack. So if you want to distribute a .app package, you could use nix to build it, and then people could download it and install/configure it according to some different scheme.
But if it's trivial to reliably instantiate the build stack, why not just ship that instead and dispense with the special format? Then nobody has to wonder if you slipped some malware in the package before you distributed it.
The idea behind NixOS is that since we must precisely define our build stack anyway, why not use the same technology to define the rest of our OS. Maybe that's overkill for some, but it sure is handy that there are NixOS users out there so when I want to use something from nixpkgs when defining my dev environment on MacOS it already has the kinks worked out.

My feeling is that most nix code is not distro managed but rather written by individual project maintainers. We only bother contributing something to nixpkgs if we think it's widely applicable.
