Correct. If this is intended for infra, it has to use devstack-gate.
That has lots of levers that we need to set based on branches, how to do
the zuul ref calculations (needed for the speculative gating), how to do
branch overrides for stable an upgrade jobs, etc.

If we think it's staying in 3rd party, people are free to use whatever
they would like.
