I don't think so. On the sites I worked on, adding SPDY gave a nice double-digit& load time benefit. HTTP/2 does not require HTTPS. But all browsers decided this was a good thing, so browser require HTTP to enable HTTP/2. And you do not need to get a centralized CA to give you certs; just use your own. HTTP/2 makes parsing way faster, which can save significant resources. It'll also cut down an ambiguity which might prevent some security issues.
