frameworkcomputer, This has been in the works for some time. With help from the NixOS community, we're set up to begin the process of introducing NixOS as a Community support distro.
NixOS community will be helping Framework with docs and related and we will provide hardware to those selected.
Some details being ironed out. This is a method of ensuring NixOS users identified as ideal candidates (a couple of selected people) can help us ensure we have Framework docs in place.
