At the end of the day, it’s just a design pattern, and it’s up to you. It’ll just be incumbent on you and those who work with/for you to keep it straight in your heads when reading Puppet materials. Roles/Profiles have been around quite some time now, and you’re inserting a “translation layer”. Also keep in the back of your head the “beer truck principle”. If you walk out the door and get hit by a beer truck, can anyone sufficiently knowledgeable of Puppet walk in behind you, pick up your environment, and keep moving without too much trouble.
