Hi Hervé,

Kayobe (part of the Kolla project) also uses
ironic-python-agent-builder to build IPA images. We use its master
branch [1], since it is the only one available. However, this has
caused issues. For example, IPA builds broke on Ussuri [2] after
ipa-builder started to use a feature of diskimage-builder that isn't
available in the maximum DIB version allowed by Ussuri upper
constraints. This wouldn't have happened had we been able to use
stable branches. Of course we could use tags, but they can break too
and can't be fixed.

So as far as Kayobe is concerned, we fully support the proposed
release model change and see no downside.

On a related note, stable branches for diskimage-builder would be useful too.
