I think they should also have 1.1 in the benchmark results, because it's still very much in widespread use.

Personally, whenever I've experienced "this site is slow", it's either because the server is really congested or there's something else taking the time (like copious amounts of JS executing on the client); both cases in which the tiny improvements (if any) of a protocol version would have zero effect.

When you consider that there's an additional huge chunk of complexity (= bugs) added by these new protocols, for small or even negative performance improvement, it really seems like there is no value being added --- it's more of a burden on everyone except those working on it.
