I think the "power" concept as a formalization of an action is perhaps the greatest advance in terms of combat made from 3E to 4E. By referencing a heavily streamlined gamespace of terms/resources (hit points, position, conditions and keywords), it has become possible for the players (through power cards / sheets) to take much of the burden of adjusication away from the DM. As such, I suppose having 4203 powers out there is not that big an issue because of how easily they are adjudicated by a group rather than everything being pushed through the DM's brainspace.
I don't understand this point. What do you mean adjudicated by a group rather than a DM? Do you simply mean the 4203 4e powers are straightforward and unambiguous and obvious to anyone reading them and so do not require a DM to stop and make an interpretation or adjudication?
