You know, we never talked about testing and version control.

Assertion: complete specification of actions in meta-data, as described elsewhere in the thread, is the easiest way to produce testing, and it also converts version control into an entirely new animal.

Also, dependencies can be tracked very well. If somebody says, "We need an A/R module in this new system, but not A/P or G/L", you can run a SELECT out of the dd for all objects that depend on the A/R subs ledger, and this is the spec that must be fed to the builder.
