If Port 80 is deprecated, we'll need to re-brand. I propose SSS... Spherical Sweeping Snare. ;)

forgive me for referring to it informally as "a null-crypto option on 
TCP/443" above. but yes, i know about that.

non-upgradable devices will never go out of style. this installed base is 
not subject to deprecation pressure. industrial control systems are far less 
tractible than web browsers. 
the analogue to this is IPv4. at some point the IETF said, everybody should 
switch to IPv6, and to facilitate that, there will be no more protocol 
enhancement actions to IPv4. if you want to innovate, do it in IPv6. 
we could say that about TCP/80. but we won't be taken seriously if use the 
word "deprecate".
