According to the spec of erlang:send/2, in order to send message to this port, the port must be registered with a name, but messages can be send to remote <pid> directly. Is it an intended design ? Do you think it is necessary to allow the following scene be possible: node A listens on a socket S, sends S to node B, and B accepts this S? Is there any considerations about this ability?

That must be a documentation oversight.

You can not send to a remote port. When sending to a remotely registered
name it is only process names that are looked up on the remote node.
