Very much welcomed. Like all protocols, unless they are pushed by industry players, they won't take off in any meaningful way. Take IPV6 for example; out compteted by its predessor IPV4 because swathes of industry players chose not to support it. I hope this is not the case for HTTP/2 as turning it on is trivial these days and more often than not, it's a small flag in a config file and boom, we have HTTP/2.
