Clear the warnings the conformance suite caused itself, so what remains is a real divergence from AWS:
- Seed conditionally required members into the base request of RDS CreateDBInstance and RestoreDBInstanceFromDBSnapshot, ECS CreateCapacityProvider and CreateService, and EC2 CreateCapacityReservation.
- Give loosely modelled members values AWS accepts: ELBv2 ProtocolVersion and Matcher.HttpCode, EKS policyArn, addonName and access-entry type, EC2 SourceRegion and STS AccessKeyId.
- Import a CA-signed certificate, key and chain in ACM ImportCertificate.
- Rewrite ACM's lookahead domain pattern as RE2 so RequestCertificate is generated, and give the integration ACM service a tenant CA permitting example.com.
- Run the service daemon-lite behind the cross-tenant boundary test.
- Accept ELBv2's common parameter validation errors in responses.
