_tablets_routing_v1flag was introduced to check if server supports tablets.As result driver needs to sync it to policy when control connection is established, which is an unwanted problem.
Initial implementation did not sync
_tablets_routing_v1for policies from execution profiles, as result tablets were not working in such case, the policy was always picking replicas from tokenmap.Let's relay on presence of tablets for given table instead, which will not require any syncing.
