I think the point is trying to get it out there, so people can share it once the original source is taken down. Doing it anonymously just prevents you from being sued.

Thanks for the tool, I’ve been missing something luke that. I had the same issue with cura, but I solved it by adding another input to my flake for nixpkgs 24.05 and installing cura from there, while everything else is on 24.11.
