Missing deps

Implements feature to be used in builder as discussed
@movitto Perhaps it's better if we wait on implementing these methods until we have clearer use cases to drive the implementation.  If someone were to report an issue or bug with these methods, I don't know that we'd have enough information to say if it's a bug or not because the intention of the methods and their use of it not clear to me.

I'm more than happy to add them when we have specific user stories.
