AFAIK/IIRC, the reason as I understood it is that ideally Chris Mason
wants to do just one more stream version bump, which means being /very/
sure it includes anything that has come up as needed in intervening
development. There's a few things agreed to be missing in the current
stream version, yes, but it's usable as-is in the near term, and before
that bump is done, everything else related needs to be in a mature enough
development state that we can be reasonably sure nothing else is going to
come up as still missing, at least for a couple years after the stream
version bump.
And without a second stream version to try, a --stream-version option
isn't particularly testable, so it was judged to be too early to add it
as an option.
