what if Amazon DNS goes down? Doesn't matter how many zones you've got... DNS remains a potential single (yes it is redundant with HA), but it's still a single point of failure.

Route 53 has had 100% uptime for serving DNS requests since launch. The API hasn't, but that only affects changes to your config. It's never stopped serving resolve requests.
