I doubt the traffic ever actually leaves AWS. Assuming it does make it all the way out to their edge routers, the destination ASN will still be one of their own. Not that the pricing will reflect this, of course.

The other problem with (interface) VPC endpoints is that they eat up IP addresses. Every service/region permutation needs a separate IP address drawn from your subnets. Immaterial if you're using IPv6, but can be quite limiting if you're using IPv4.

Sounds like a good reason to use IPv6.

There were still a couple of services/features that choked on IPv6 last time I looked (1.5-2 years ago) but it works with most things and they do seem to be making progress on the others.

I don’t know any software that doesn’t work with IPv6 as of 2021.

Just some internet services that haven’t upgraded. (But fixed by NAT.)

		There's a matrix provided by Amazon themselves listing the level of IPv6 support in their various services: https://docs.aws.amazon.com/vpc/latest/userguide/aws-ipv6-su...
