Imagine if we were stuck in a world with a large bloc of users running MSIE6 regularly accessed web servers running 40-bit SSL2. Neither clients nor servers ever bother updating, because it still works for them. That's essentially where every other protocol is. HTTP gets all the energy, active development, updates regularly rolled out. Meanwhile if you tried to make, say, FTP more rational by transmitting data over the control connection, nobody would be able to use it since all the servers are still running 25 year old wuftpd with the minimal patches to not get pwned and they have no interest in updating (if they even remember the servers exist). Personally I think we've lost something valuable when only one protocol exists, but I'm one of those Luddites who still reads email with Thunderbird so what do I know.
