It's both.

Docker is already quite modular. For example storage and execution backends are swappable using a driver interface. Image storage is a separate binary. Clustering and machine management are a separate binary. The primitives for interacting with kernel namespaces an cgroups are in a separate project called libcontainer. We are developing authentication and security features in a separate repo called libtrust.

And at the same time, I believe we can do better, and made it a high-level goal of the project to improve modularity. I am simply stating that high-level goal.
