Same comment here as earlier. If we do a v3, it might not be compatible
with v2. Shouldn't we bail if the user asked for it?

I actually kind of wonder if we should just die("BUG") here on seeing
"0". Is this low level the right place to do the "default to v1"?
Because eventually we're going to want to default to v2, I would think
(after a few years have passed, at least). It seems like we should be
making that decision centrally when we init the transport options.
