"Doesn't work reliably enough" doesn't answer the question of why Google didn't test HTTP/2 against pipelining. None of Google's performance improvement claims compared to pipelining, and they've never demonstrated or quantified an actual real-world head of line blocking problem (ironically, other than Google Maps loading very slowly in HTTP/2 because of a priority inversion). Will Chan is the guy that wrote "it’s unclear what these intermediaries are". Oh well, there's some bad software out there, let's just make a whole new protocol /s. Fix the bad software, or at least find out what it is. If it's malware causing the problems, you don't need to make a whole new protocol you can just get rid of the malware.
