No, TCP was designed to do long term connections, survive 
disconnection of lower layers, etc. Bear in mind one of the first 
applications was TELNET, and next up FTP, both of which, I think, 
were actually key protocols that TCP had to provide better support 
for than NCP - note that although FTP exhibits the precise behaviour 
you describe in its data connections, and early HTTP also behaved 
like that (and got an IESG note partly because of this), it's 
entirely the opposite behaviour with pretty well everything else, 
including FTP control connections, etc.
