Good luck! My experience of Nix, and similar "robust engineering" solutions like Bazel is that there are a handful of people that get it, and see the benefits. But there are hoards more that think you should just write hacky shell scripts and bugs don't really matter anyway.
There are also the people who get it and see the benefits, but don't want to put up with the work required to have your system or environment managed with Nix. If this tool simplifies things, it could get traction.
