This just seems like HR talk and dropping coined terms in an attempt to give something life that doesn't or needn't exist.  Everything described should be intrinsic to the DB development team.  The CIO or CISO would meet with them, define business need and process and they would develop it, maybe even with a project manager's oversight.

Seems to me this is the emperor’s clothes and is an unnecessary position.  DBAs should have an understanding of business flow and data management needs and offer solutions that will provide the best ROI for the business; that is why businesses hire them.  Adding another "A" to a title doesn't change this, but it is a nice way to try to get more money out of clients.
