This is unsafe because it allows us to "forget" store objects we would have otherwise referred to with the string context,

Safe operations "grow" but never "shrink" string contexts.
[`builtins.addDrvOutputDependencies`] in contrast is safe because "derivation deep" string context element always refers to the underlying derivation (among many more things).

Note that `derivation` is very bare-bones, and provides almost no commands during the build.
Most likely, you'll want to use functions like `stdenv.mkDerivation` in Nixpkgs to set up a basic environment.
