Ok, so I would suspect that you got the SID simply because the controller is still used to it (as you are!) and they simply forgot that the rule has changed. I would be very surprised if the answer to a question “Why did I get a SID?” would not have been a sort of “Uh – ya – you are right – cleared for standard missed approach…”
Haha maybe.. if it happens next time I’ll give such question a try
