The thing is, when it comes to AWS, its not like everyone is going to suddenly migrate off because of a DNS issues. If a company that runs on AWS is not making money, its very likely that their competitors are neither. So more optimized solutions are not really worth it.

In a perfect world, everything would have a unique IPV6 address, and we wouldn't need DNS. Instead of NAT, you would just have any computer/vm that wants to be connected to the internet tacked on to existing address space, and then instead of DNS record being synced, you just use the address directly, and routing would take care of everything.
