Yes, we have done this migration in Victoria release cycle with two community-wide goals together
with the direction of moving all the CI from devstack gate from wallaby itself. But by seeing few jobs
and especially 3rd party CI, we extended the devstack-gate support for wallaby release [1]. So we 
extended the support for one more release until stable/wallaby.

NOTE: supporting a extra release extend the devstack-gate support until that release until that become EOL,
as we need to support that release stable CI. So it is not just a one more cycle support but even longer
time of 1 year or more.

Now extended the support for Xena cycle also seems very difficult by seeing very less number of
contributor or less bandwidth of current core members in devstack-gate.

I will plan to officially declare the devstack-gate deprecation with team but please move your CI/CD to
latest Focal and to zuulv3 ASAP.
