If git is an auxiliary tool, your entire programming environment and language are "auxiliary tools". Today being able to persist and distribute multiple versions of source code is table stakes for being a programmer. If we're really talking about "jobs", that's probably more central than writing code - a release manager might do nothing but manage git minutia and still provide value, a programmer that can't give anyone else the code they've written provides nothing.
