Thanks for your feedback. We do mention parallelization in the designdoc, it's just not implemented yet. It's quite easy to add though. We have a lot of features spec'ed out, but not implemented.
I would appreciate if you elaborated on separating step definitions from dependency definitions. In my mind, they are the same thing. If you mean that steps might not be connected by input-output relationship, but still have dependencies, Drake fully supports that via tags. If you mean that steps might be connected through input-output files, but not depend upon each other, I don't frankly see how it's possible. And if you mean some other syntax which more clearly separates the two, Drake supports methods which achieves exactly that. If you mean something else, I would love to see an example.
