I'm excited to see where this discussion goes.

If we decide that a portion of swift being in Go (or C++ or Rust or
nim) is a good idea, (just as we've decided that devstack being in
shell and portions of horizon and tuskar being in Javascript is a good
idea) I'd like to caution people from thinking that must necessarily
mean that our general policy of "python" is dead. The stance has
always been "python unless there is a compelling reason otherwise". It
sounds like there may be a compelling reason otherwise here.

As John points out more politely below, OpenStack can experiment with
language without turning ourselves into a feckless standards body.

This I agree with. :)
