I don't really expect anyone to review this, setting up a NixOS machine is pretty niche, but it is helpful when doing android work on my desktop.

Do we want to land this diff?

Repeating my feedback from D4483:

Was chatting with @atul and neither of us is really sure what the product impact here is. The team (outside of @jon) doesn't use NixOS, so the only benefits I can see here are:

1. To improve @jon's personal custom workflow. Here, I wonder if we should be spending cycles supporting a custom niche use case, as opposed to having @jon use macOS primarily like the rest of the team
2. To provide an alternative to the CI build that we currently do with Debian. Here, it's not really clear if the change will be that impactful

At a high-level, I think we should be prioritizing Nix work that has an immediate impact on dev velocity and dev experience across all devs on the team. Until the whole team is actively using Nix for the primary development workflow, I'd prefer if we could deprioritize any other Nix work.

To help make the prioritization super clear, here are some clarificiations:

1. NixOS support should be deprioritized in favor of macOS Nix support
2. CI Nix support should be deprioritized in favor of dev environment Nix support
3. Nix as a replacement for Docker should be deprioritized in favor of Nix as a replacement for Homebrew and the dev environment instructions

I want to talk through the pattern of @jon using NixOS while trying to support the rest of the team (who are using Nix on macOS) in our 1:1 later today. We can follow-up on this diff after that.
