I'm not sure why you feel the need to argue with almost every suggestion or bug report people make. This is a perfectly reasonable suggestion and there's absolutely no reason why it shouldn't be implemented.

/var -g allows you to create a global variable, so it should have the same features as /set does. There's not really any reason why it shouldn't. And I doubt something this trivial will be "keeping Khaled busy."

If you have nothing useful to say, don't say anything.
