don't ever change, @yarikoptic

Hi @mickeypash, thanks for your interest in taking this on! This is a good impetus to start laying out some guides for developers, so I'll use this issue as an...

On further inspection, I think this issue can be broken up into several steps. The Rekognition API supports a number of services that don't require S3. In boto3's Rekognition client,...

That would be great! Let me know if you want any implementation pointers (we'd probably want to put this in the base `Transformer` class, so it's available throughout the hierarchy)....
