gen_tcp and message handling

Once you open a port with gen_tcp, by default all messages to that
port are sent to the controlling process as normal Erlang messages.
You use the receive statement to get them. Slick!
When sending messages this isn't true. You send a message via
gen_tcp:send/2, not via the bang operator. Is there a reason that
you can't simply send messages to the port returned by
gen_tcp:connect? The main reason I'm asking is that it would be nice
to register the Erlang port returned by gen_tcp:connect, then send
messages to that name, rather than having to pass the TCP port number
all around.
