I'm deferring moving any more API calls to taskflow. We've moved create_volume to taskflow and I think we still have a long way to go before realizing the benefits here and I'd like to get at least one API task figured out and solid before migrating everything. The taskflow implementation adds quite a bit of code and complexity that I want to make sure is worth the investment.
