Maybe a bit early since there's no NixOS module yet, but now that it's published on nixpkgs, I thought I'd put this here.

I wasn't aware that Zed was available on Linux yet - thanks for the heads up!

And you're right, it may be a good idea to wait for a NixOS/Home Manager module to be created before working on this.
