I think it makes sense to take the time to get it right. Every version of HTTP will effectively have to be supported by just about every server and client forever or otherwise the web will break. An incredible aspect of the web is that Tim Berners-Lee's first website back at CERN still works in modern browsers. Same with things like basically the entire Geocities archive. When it gets to core infrastructure like HTTP you can't just iterate quickly and expect the entire internet to constantly upgrade along with you. What works for early stage lean startups won't work here.
