(Get the code!)
I belive too that it is fundamentally not supported to downgrade or crossgrade. From MySQL x.x to 5.5 to 5.6 users / database admins have been responsible for backing up their data and upgrading the database without having the option to go back. This is quite sensible and there is no point in trying to copy /var/lib/mysql-5.5 to say /var/lib/mysql-5.6 when most users have no intention to downgrade on the same installation (they will do it via backups if they must), and there is probably not diskspace to duplicate the database on each upgrade either.
There is nothing we can do to enable downgrading in particular.
The bug is about the user experience: how users are notified what happens and how dpkg is aborted into a broken state.
