I do not frequently comment here!
However I wanted to state that this is exactly what I intended to happen when I created the profiles directory of NixOS.
The intent of creating the module system is that people who have the knowledge can contribute and help others who do not. This was never meant to be an elite restricting mechanism, this was meant as a sharing mechanism.
Today, I find that many modules exists in NixOS, this is awesome and I am thankful to all the community. However, providing consistent defaults for NixOS is one other aspect of the future of NixOS which should not be neglected!
SNM and musnix are great examples of that. These should literally be first class citizen in the NixOS ecosystem. The fact that most people are using bare NixOS today is the anomaly.
