You're right, and I did think of that after I clicked "reply". What I meant was that a company with so much resources doesn't seem to have that capability. Even with such a large size, I would imagine Amazon of all companies would have the resources to say "this is
the design, now get on board" and make it happen.
This goes for other aspects of AWS as well, such as consistency in the way services report to CloudTrail or are referenced in CloudFormation. Overall there just seems to be little coordination amongst AWS teams, and that's always surprised me.
