The approach for the XML-RPC work was to first get XML-RPC support into 
the tree and then build a standard interface.  Building a standard 
interface requires refactoring (which will be simplification) to get rid 
of things like S-Expression configs.  To get rid of that, we have to get 
rid of the S-Expression/HTTP layer.

This whole reasoning is outlined on the wiki page.
