I'm concerned about this "wait an arbitrary amount of time before falling
back" semantic. When we first implement it I expect to be falling back
almost all of the time. In fact, most developers would probably have a
better experience if we never attempted h2 at all. We could race an h2
connection with an h1 connection but that seems suboptimal.
