Addition of strategy layer to architecture domain as defined by togaf9

Recently i read an article by Tyson Brooks 0n "Principles for Implementing a Service-Oriented Enterprise Architecture " . I specially liked the diagram given below. I particularly liked the idea of strategic architecture layer in addition to 4 architecture domain - Business, application, Data and technology, as defined by togaf9.

It will be good idea to add a specific layer - strategy layer, over business layer . The strategy layer will deal with enterprise vision, mission, values, motivation, goal and strategy. Business layer should focus on business processes, business rules business measures and GRC(Governance, Risk and Compliance) . Addition of fifth layer will make the over all architecture much more intuitive and closer to real business world .
