Flakes: idiomatic way to pass inputs to configuration.nix

I use flakes to manage my configuration.nix. To install a custom (non-flakes) package, I specify it as a flake input, and then add it to environment.systemPackages directly as a nixosSystem module.

But the above is HACK. As you can see, it belongs to the well-positioned module ./features/email/himalaya-client.nix.

The trouble is, this module apparently cannot be parameterized to pass the inputs from flake.nix.

Maybe I’m missing something. What’s the idiomatic way to approach this?

Pass it in specialArgs and then it’s just available as an input to your config modules.
