Whoa... being in the right place at the right time best falls in the category of "politics", not technological innovation/evolution.

Your suggestions revolves around the assumption that today's DBMSs are a capable environment for application development. This is unfortunately not the case and is the reason that we have "application servers" and such. It is clearly desirable to remove the conceptual "middle tier" and reduce overall application complexity. However, this layer can only be eliminated by a aptly capable DBMS. Existing systems can be preserved, but only as a "storage engine" underlying a more capable DBMS.

I will respond more on your proposed "layers" in another posting...
