 At **[1]**, the supported systems are specified. I personally use `x86_64-linux` and `aarch64-linux`, but I also usually support `x86_64-darwin` and `aarch64-darwin` in public projects.
 If you want to support any system, you can use [`nixpkgs.lib.system.flake-exposed`](https://github.com/NixOS/nixpkgs/blob/374e6bcc403e02a35e07b650463c01a52b13a7c8/lib/systems/default.nix#L58) at **[2]** instead of defining your own list.
 
-Because the definition is right inside the flake, you can tweak what gets passed to the function. For example, the [flake for RedoxOS-development](https://gitlab.redox-os.org/redox-os/redox/-/blob/cb34b9bd862f46729c0082c37a41782a3b1319c3/flake.nix#L38) I contributed[^1] this to passes the custom rust-toolchain.
+### Example variations
+
+Because the definition is right inside the flake, you can tweak what gets passed to the function.
+By doing that, you have to explicitly add the new identifier to each part that uses it, instead of having a global `let` binding that is implicitly used.
+`system` being available here is another bonus, as otherwise this would require duplicate `let`s everywhere.
+
 An example for how to do it is already right there: at **[3]**, `pkgs` is provided.
+Some real-world usages I wrote or encountered:
+
+- [servicepoint-life flake](https://git.berlin.ccc.de/vinzenz/servicepoint-life/src/commit/5f5e10d39f09f4d60b4301e76f0158636afee6d1/flake.nix): passes in initialized `naersk` instance and a shorthand to refer to packages defined in the flake itself
+- [RedoxOS development flake](https://gitlab.redox-os.org/redox-os/redox/-/blob/cb34b9bd862f46729c0082c37a41782a3b1319c3/flake.nix#L38): uses it to pass a custom rust-toolchain
+- [my NixOS flake](https://git.berlin.ccc.de/vinzenz/nixos-configuration/src/commit/3d27f554015ece713fa22fe829d711b430d6bbda/flake.nix): uses something similar for per-host config
 
 Another possible tweak: You may want to define separate supported systems for each output.
 This is useful, for example, if the target environment you're developing for cannot support a development shell.
 
+## Conclusion
+
 For me, the trade-offs are worth it, as they provide greater transparency and control over the flake configuration.
-
-That being said, I fully acknowledge that `flake-utils` can still be a great choice for many people.
-It simplifies things and reduces the need to write boilerplate code, which can be a plus depending on your needs and workflow.
+For you, this may be different, in which case keep using it!
 Ultimately, it's also matter of personal preference.

-[^1]: If you check the history, you will see I am not mentioned. I am still a bit salty about that, as it was my first contribution to a bigger OSS project.
