"strictly asymmetric protocol, not intended to be used directly between
players" does not imply "All communication is initiated by the controller".
It would be reasonable to allow a player to ask the server "how much time
do I have left?", and "how much time does my opponent have left?". As
far as I know, GTP does not support this.
