Well I hope you are right that it does not take much out of the server - with 2 request for each game - some players playing 1,000+ moves a day (2,000 time it checks to see if user is on-line, and if so find out what user is doing & display what they are doing on the screen - just for 1 player!).
I know Fencer said it would take too much out of the server to be able to "move to next game according to time". I would think this would take more out of the server as this new "nosy opponent" option, but I'm sure it does take some. :-)
