Definitely. But one of the nice things about a lot of the AWS stuff is that you can build on the same infrastructure you'd use if you wanted to scale up. So if you have a toy project that ends up being more successful than you expect, it's pretty easy to just add resources. For example, DynamoDB is ultra cheap for the lowest usage levels, but simply by reserving more capacity you can scale up with absolutely no changes to your app. Makes it easy to prototype or play on the real system and not have to re-do your work later if the project becomes more than a toy. I guess since this is MySQL-compatible it wouldn't be that hard to migrate from MySQL to Aurora, other than moving the data...
