How many times have you seen a message saying "move out as late as possible!". You can call that Meta-gaming.
Or how many times have you ever set movement late yourself, so that the enemy would never know? Isn't it meta gaming too, playing around the time you know as turn? I know I've made late turn moves, does it mean I and everyone else who ever did it ought to be punished?
No, that's a realistic strategy, one that real armies use.
