Totally agree, and also this was one of the most powerful aspects of using nix development environments: when everyone is guaranteed to be on all the same (recent) versions of bash, make, awk, sed, and any other system deps, you can confidentially write your scripts knowing the whole team can use them, without having to deal with Mac users’ scripts breaking because their bash is old, or because somebody doesn’t have jq installed, or whatever.
