Personally, I try to avoid using "nix-shell" as much as possible because I
want "nixos-rebuild switch" to atomically install (and upgrade) all the
software that I usually need, including development packages.

With nix-shell, I risk having the packages I need become outdated (without
me noticing) and/or become garbage collected (which I do every day
automatically) and unavailable if I lose Internet access (e.g. because I'm
traveling).
