My apologies for not meeting your bar. I guess you missed the parts where it's faster in a lot of other cases too, and not slower in any.
To me, the fact that it's not slower at all is the big win. I didn't anticipate that the results of this are going to say "this is 5x better". The stereotype is that if it's over HTTP, it must be slower.
And by every measure, it's not slower. In cases, that may be edge to you, or don't care about extra latency, they're still improved. Why would you not want something that's generically better?
There are many other things that are beneficial with using HTTP as a transport that haven't even been discussed here since this was entirely focused on performance. Without at least matching in performance, not many of the other things would matter.
