Well, you could do the heavy lifting with an awk script: 

 If the current line is a pin,
    set the diameter of the pin to zero and add a hole flag
    ouput a round pad with the diameter of the pins annular ring
 else, 
    output the current line unchanged.

IMHO, the copperless pin solution is superior. It models the layout like 
it is in reality.

That said, both autorouters have a problem with user level configuration, 
or rather the lack thereof. Features that would make auto routing a much
more viable option than it is now:


* alternatively minimize via count, or minimize overall track length

* options to not autoroute particular nets/pins/components

* track parameters that depend on the net it connects

* preferred routing direction of a layer

* Non-copper avoid-areas with different levels of importance. 
  (prefer-to-avoid --> avoid at all cost)
