And then you still have more stuff to manage now based on the slim chance that one day years down the road you might rip your entire multi Az redundant infrastructure, your databases, etc with all of the read replicas to another provider....
And this doesn’t count all of the third party hosted services.
Aurora (Mysql) redundantly writes your data to six different storage devices across multiple availability zones. The read replicas read from the same disks. As soon as you bring up a read replica, the data is already there. You can’t do that with a standard Mysql read replica.
