And I am in no way asking for a fast-lane or special treatment. I would just like to be able advertise this as: "If we write the code, someone is going to look at it and helps to get this merged for Bobcat."I think that is a fair statement. Just note that others in the community may not have a lot of time to co-develop on it.
We then gladly invested the time to implement and discuss the
      feature we anticipate to use ourselves,
      but which I also believe is a big improvement to the scalability
      and stability of provisioning the DNS secondaries.
      Coming back to my point ... You made clear that co-development was
      not very likely to happen, that was very transparent.
      
      But this discussion implied that review of a submitted
      implementation was something you
      or others in the Designate team would be willing to do.
    
There now is a first iteration for support of Catalog Zones pushed:
* https://review.opendev.org/c/openstack/designate/+/885594
PTAL and start commenting / reviewing so we can iron out any issues to have this ready for the Bobcat release.
The implementation, while receiving some feedback and requiring
      some iterations is now there for review.
      There is a corresponding change for devstack to support this
      feature, see all changes via [1].
We did miss the Bobcat release, likely for good as that gave us
      more time to work out the remaining issues.
      But now we'd really like for this feature to be finalized and
      merged for 2024.1.
      And while code has to be of good quality before being merged, at
      some point a feature just has to go into a release 
      for people to actively use it in production and to be able to
      provide feedback on potentially missing settings or any other
      issues.
    
I'd really appreciate if you or anyone from the Designate team
      could kindly respond on your intentions for catalog zones 
      towards the Caracal release.
    
    
    
Thank you and with kind regards,
    
    
Christian
