It seems like the on demand feature views are not being consumed by the jobs anywhere - is that intentional?

Why are we changing the API for the base class here and adding these fields? Are they necessary?

NVM, I see why they're needed now. While I think this is okay for a first pass I want to see if we can get away from adding these additional fields on to the job. I think they are pretty inelegant for a user to have to implement themselves.
