What makes this different from https://aux.computer? And with just ten people - such a small community, to maintain what, a parallel fork that will eventually be forced to accept patches from Nix repos? How does it protect against, let's say, corporate decisions? Wouldn't that seep into their project too? Not trying to demotivate them, but I fear that this could be the fate of their project.
There's Guix, which is an official GNU project. If anyone is willing to learn a little bit of Guile Scheme - look, the language is great, the project isn't contaminated with multiple scripts, project skeleton is much better, the modules are well written, so why not move over there? Sure, it's still in the early version, so some stuff will be hard to work with, but personally, I think it's a really nice hard-fork.
