The main deficiency I can see there is that it is aging data already and 
measures what the situation is in a market where middleware authors were 
given no incentive to support the feature.

The use case for Upgrade:HTTP/2.0 in particular is now providing that 
incentive for middleware implementations to support Upgrade better and 
indeed seems to have stronger support from middleware than end-software 
authors. Working with us rather than assuming we we never implement a 
needed feature will go a long way towards seeing that feature rolled 
out. The results of that single test could change dramatically in the 
coming years and are very likely to flow along with HTTP/2 rollout.
