I agree that it will have to make "action" a special parameter (or could be extracted from the dict), but there are several benefits:
 * Ability to easier partition server farm to create a cluster dedicated to certain actions - like parsing (requested by parsoid team)
 * webserver access log files will contain the action even for post requests
 * No need to introduce api2.php just yet - we can determine new version by request style
 * Future core version changes can be done in the style api.php/action/2?...
 * Shorter URL
