Migrate to KeyMap?

[RobertFischer]

Let's not hold up the Amazonka 2 release for it, but whenever we get around to Amazonka 3, would you be willing to consider moving from HashMap Text to Aeson's KeyMap, at least for the DynamoDB requests and responses? I have no idea what this would look like in terms of a code change, but it'd almost certainly be more efficient and easier to work with now that we're using Aeson 2.

I think this thread predates the custom AttributeValue type in amazonka-dynamodb, and for other services I'm not sure that KeyMap makes much sense (though I'm happy to have that discussion).
