Yeah, similar experience here. One pattern that was helpful for us was defining a nix file that just contained a mapping of names to lists of packages: dev, ci, and so on, so that if you wanted to install something that was on the nix search page, you could just go toss it in there and immediately get it locally. It also made it clear which package sets would wind up where, and allowed recursion so you could say that like dev was rust-base ++ rust-dev ++ js ++ common, or whatever.
