Would it be beneficial? Yes. Is it necessary for most cases? No. I do think, however, the moment when you infrastructure becomes defined by code (eg. you start using any CM system) then you should be training your sysadmins to program more and duct tape existing solutions less. Operations become vastly easier to scale and maintain if you can defer their logic to actual services with clearly defined business logic rather than a mess of ansible configs and bash scripts.
