There is plenty of terrible Dockerfile out there. I would vastly prefer to see images or Dockerfile generated by some well written buildpacks. I like to think about buildpacks as reasonably written Docker templates. Yours is 5 lines long, but many are others are more complex and could benefit from having a multistage (base stage with common dependencies, build phase with build dependencies, run time with the result of the previous plus some extra runtime dependency), setting up a custom user/group for extra security, optimizing execution order which vastly affect the time to build the image, etc. I am considering using them to make easier for my colleagues which are not used to Docker to containerize their application as well as using them as template system for Dockerfile handled centrally, which do not need any kind of manual merge/alignment afterwards.
