I'm sure that some services still have a name outside of TCP/IP.  Besides, 
it's only an extension, which does make a bit of sense since you would just 
choose not to use that extension in the case where you're not going over 
TCP/IP (analogous to an XMPP server choosing not to allow external auth if 
the connection is not going over TLS.)

Funnily enough, if we'd had naming in TLS from the start, there probably 
wouldn't even *be* STARTTLS since everyone would be using the better 
method. :-)

RFC 2817 is still neat though.  Funny how web browsers, despite being the most 
used Internet app around, or so they say, are so slow to follow standards.  
We should have SRV for web browsers too, but hardly anyone implemented that
