Disclaimer: AWS SDE The focus on consistent behavior and once launch, never deprecate practice has caused many headaches, I personally know of control planes specifically written to accommodate old behaviors that a few customers had years ago even when the entire service has been updated. But IMO this is still much better than deprecating production services and behaviors on the fly.
