It's not a case of buildpacks vs dockerfiles. They both solve different problems with different solutions.

Buildpacks fit nicely into the heroku way of doing things. But at any medium to large sized engineering organization, there's no way they could satisfy the requirements for even a simple majority of services that using a Dockerfile provides.

Could you give an example of such requirements?

Disclosure: I've worked on Cloud Foundry Buildpacks twice and worked on this latest effort until recently.
