This is a very contentious topic, you can see my initial take on this in

The problem is that's not really true. i.e. consider you get postfixed pulled in by postfix | mail-transport-agent and the new distro release changes it to exim4 | mail-transport-agent as we picked a new default MTA.

Does this mean we should, by default, replace your MTA and require you to have to configure a different one?

You will be able to do this (pick the same automatically installed packages given the same set of manually installed ones; installing missing Recommends, etc, by using --fix-policy and some more options perhaps).

As for configuration this is worse, files managed by ucf have 3-way merging but it's not automatic and most configuration isn't managed by ucf but by dpkg.
