Today, a shard that is not yet added to the cluster is exposing the router port if the embedded router is enabled. If the shard identity document is not yet set, the node may crash if petitions are accepted through the router port, because some shared (shard and router) internal modules are not initialized.

Goal

We need to make the router port not accept connections until the shard identity document is set in order to not process petitions when modules are not initialized.
