Hmm not really. That's the toy use case. Nixery builds your expression and gives you a docker container. By default you can specify like "git and tmux" as they are the example toy expressions HOWEVER it becomes a different beast when you use it in monorepo situation see https://GitHub.com/ghuntley/ghuntley and https://code.tvl.fyi/

My understanding is that's still "use Nixery to build docker image with packages installed", but it's a different set of packages being served.

What use cases / dynamics arise from doing that? & what's the value-add from doing that with Nixery compared to just otherwise building docker images with dockerTools in Nixpkgs?
