~~I get the impression there are several others, too, but that one is of especial interest to me~~ Wowzers, they really are much better now:
aws --region us-east-1 ec2 describe-vpc-endpoint-services | jq '.ServiceNames|length'
459
If you're saying "other services should offer VPC Endpoints," I am 100% on-board. One should never have to traverse the Internet to contact any AWS control plane
Those are VPC endpoints, not gateway endpoints.
