There exists a package: A module is currently missing.
Uh I was pretty sure I checked in my local nixpkgs checkout. Weird, I wonder if I just made a typo while checking. Sorry about that. We can leave this issue for the module part.
It looks like the maintainer is Have you started work on a module already, or would you prefer someone else step up to work on that part? I haven't dealt with creating modules in the past, but I'd be willing to learn.
I haven't dug into making a module previously. I suspect there's a bit of ugliness around the setup and configuration decoratively, but I'm happy to work with someone on it. Shall I start a basic PR?
yes please :)
