So afaics there is nothing that can be done from the Debian GNOME team
side, right?

I see that #863820 is still open and apparently also affects other
upgrade paths. Shouldn't this be bumped to RC?
What are we going to do about this? A failure to dist-upgrade our
default desktop environment is pretty bad.
Is there some known workaround which we could document in the release
notes at least?
From what I can see, wouldn't it be better to drop the the Breaks:
tzdata-java from openjdk-8-jdk-headless again?
