Ohh. I failed to realize the talk's about bookworm, not trixie, - even
if everything mentions that!  And you're proposing to update it, not
to introduce a new backport for trixie.  Heh.

Yes, I did make postfix backport to bookworm, - in order to have the
changes in packaging there - namely the multi-instance and logging
changes.

Okay, lemme re-read what you wrote once again with this in mind.. :)

And now I'm confused.  Usually when I do a backport of version Y,
I start with that version Y, exactly, and re-apply whatever changes
needed for backport of previous version X, X~bpo12+1.  So the history
(d/changelog) for Y~bpo12+1 does not include changes between X and
X~bpo12+1.   In your case though, it looks like you started from
X~bpo12+1, and picked up the subsequent changes from the master
branch, so version Y in your new history also includes changes
between X and X~bpo12+1, which are missing in actual version Y.

Maybe I miss some tooling or a common way of doing things?

This is why I mentioned the changes you "did not" put to the
changelog - because they're already there before.

Thanks,
