The protocol is not really replaced, it's wrapped.

Before:

  SocketTransport <- UserProtocol

After:

  SocketTransport <- (asyncio.sslproto.SSLProtocol
     <- asyncio.sslproto._SSLProtocolTransport) <- UserProtocol

That way, the same SocketTransport (but it could be something else, e.g. a pipe transport) is always bound to the event loop; we simply insert a processing layer in the chain between the original transport and the final protocol.  There are two distinct objects so that the SocketTransport sees a protocol and the UserProtocol sees a transport; but those two objects work hand in hand.
