Mathieu,

though this ssounds all pretty structured and logical, I think I know where these issues come from.
Most users will just go the all-in-one upgrade way by 'apt-get upgrade' and hence would not be able to fine-tune settings as in the APT line I've quoted from you above.

What you've suggested must be executed BEFORE even THINKING about using apt-get upgrade.
Because then, the network-manager including its dependencies will already have been crossed out from the list.
