I guess that request is related with the Richard's concern mentioned before in 
this thread.
Adding such information by default in the dired buffer may slow down 
things too much.
If the ls command would add a new switch to show such recursive 
directory sizes, maybe it could be reasonable to implement such option. 
Otherwise, i don't think it could be practical.
