Yeah, the lack of HTTP/2 support has been a long-standing issue with Heroku. They just shipped HTTP/2 terminated at their router [0], and have it on their roadmap [1] to support HTTP/2 all the way through. But it seems like it's at minimum a few months off. (As for VPC peering: the moment you need that, it sorta feels like Heroku is no longer the right place to be, even ignoring the costs.)
