The generator declined to write one, for the reason given. - ApplySecurityGroupsToLoadBalancer (`never-probe`): Replaces the security groups of a load balancer wholesale rather than adding to them, so a probe would strip whatever rules the caller's own load balancer relies on. - AttachLoadBalancerToSubnets (`never-probe`): Puts a live load balancer into another subnet, which changes where it accepts traffic. - DeregisterInstancesFromLoadBalancer (`never-probe`): Takes instances out of service behind a live load balancer. - DetachLoadBalancerFromSubnets (`never-probe`): Removes a load balancer from a subnet, and with it every instance in that subnet. - DisableAvailabilityZonesForLoadBalancer (`never-probe`): Takes a whole Availability Zone out of a load balancer. AWS documents the instances in it as deregistered and the zone's capacity as lost immediately. - EnableAvailabilityZonesForLoadBalancer (`never-probe`): Adds an Availability Zone to a live load balancer, changing where it serves from and what it bills for. - RegisterInstancesWithLoadBalancer (`never-probe`): Puts EC2 instances into service behind a live load balancer, sending it traffic it was not meant to receive. - SetLoadBalancerListenerSSLCertificate (`never-probe`): Replaces the TLS certificate a live listener serves. - SetLoadBalancerPoliciesForBackendServer (`never-probe`): Replaces the policies applied to a backend port wholesale — an empty list removes every one of them. - SetLoadBalancerPoliciesOfListener (`never-probe`): Replaces the policies applied to a listener wholesale, which is how a listener loses its stickiness or its cipher policy.
