The convenience for me would be in time shifting the labor. Sometimes (read: often) I want to sit and zone out for 15 minutes, but I almost never want to deal with transferring a powdered substance from one container to another, especially not after the rigamarole of loading the dishwasher. In theory the powder could go in first, or at some other time, but my brain just isn't like that.
