I agree that having such a facility would be great. Unfortunately this
is way out-of-scope for this bug report and would not only involve apt,
but any tool really which can be used to dist-upgrade a system
(aptitude, cupt, ...) and might even involve dpkg itself.

This would need coordination and planing from various different parties.

If such a facility existed, we'd be happy to use it.

If you want to get the discussion started on that, you are more then
welcome to do so.

Feel free to file a bug report against the release-notes package
including a proposed text.

Debian is built on users participating, especially if it concerns their
particular use case.
