They have actually been making S3 _more_ consistent over time: in the newer regions you get e.g. read-your-writes for object creation. DynamoDB also supports consistency, though still defaults to eventual consistency if you prefer.

In my mind, there's definitely a trend towards consistency here. I'd love to see an AWS blog post about the reasons behind this!

We should be glad. Eventual consistency is hard to reason about, particularly when its tradeoffs have to do with other people's systems...

US Standard now provides read-after-write consistency when accessed through the Northern Virginia endpoint [1].
