The snark here is unnecessary and completely disconnected from how people use these systems in the real world.
Deferring to “it’s in the notes!” means nothing if you have more than a handful of packages on your machine.
You should also clarify the assertion that packaging affecting testing target won’t eventually hit stable, because that would be a major change that I haven’t heard about.
Oh, the horror of being in unstable/testing channel and ignoring the change notice which has been shown automatically during apt-get upgrade.
