Even a small thing like that is a great example of how Google and AWS treat backwards compatibility fundamentally differently. AWS
really doesn't EOL things, no matter how 'minor' the impact would be. Look at SimpleDB - it was launched in 2007 and has very clearly been deprecated in favor of DynamoDB[0]. It's not even in the console(!). Yet, it's still operational and usable with the AWS CLI. Everything about it screams "could have been EOL'd years ago", yet AWS dogs on in supporting it and everything else it's ever released until the end of time.
