I would hope that the majority of players would be mature enough that if something was released, they wouldn't cry about not being able to double click fast enough. I'm sure it's bound to happen, but it still falls in the category I spoke of above - why disallow a feature simply because some people would whine?
If the majority would benefit (and I'm sure this would go to a person working a different request than say, network latency) then isn't it a good feature?
