Security Groups were initially an EC2 only concept. You couldn't write security groups for SQS or S3, and they came about alongside EC2.
Obviously EC2 is no longer the only service that utilize security groups, but it's an artifact of when they were.
(I'm not saying this is how it should be, just answering the 'why' part of the question ;))
