Working without javascript requires development time. Running old versions of HTTP doesn't. Version 1.1 is going to be fully supported for a long time.
Running old versions of HTTP requires nothing because people will need to support legacy devices for a long time, and it's obviously already implemented in all major components (Servers, CDNs, Clients, etc.)
Still not getting it. Every site is hosted. The hosting company needs to spend money on HTTP/2, and be allowed to use it. The networks need to allow TCP through. All the steps down to the transport layer now require legacy maintenance.
Lots of things need to happen for HTTP/2 to 'stay alive'.
Your use of the future tense does not convince me.
Downvoted because of the "you geniuses". You're making a fair point that I hadn't thought of yet (I'm also a fan of Tor), but the delivery method is just plain rude.
