I'm much newer user and admittedly the documentation is not great, so I've used forums and IRC a lot and from what I've gathered, the movement is towards declarative reproduceability. This is the reason for the development of flakes. I saw installation of packages using nix-env in many search results and tutorial pages but newer comments seem to indicate that this is no longer recommended, and it fully makes sense to me. I want to get my machine back to the same state using my config checked into git, and installing imperatively using nix-env clearly goes against this.
