It's 90% there... but not allowing foreign keys [1] (=cascading delete) means that this solution becomes equal with DynamoDB (Serverless + Scale to 0 as well) because products will either be built for it from day one or never support it with a full fledged DB server instance that is 100% up in mind. Unfortunately, didn't find a lot in-between.

I like foreign key constraints as much as the next guy, but they are hardly the only difference between MySQL and DynamoDB. For example, you should be able to use Rails/Django/Laravel without foreign key constraints, you can use off the shelf SQL clients or BI clients, etc.
