I see that point due to the different default for this behaviour --
which is one reason why "aptitude upgrade" is deprecated in favour of
"aptitude safe-upgrade".

But apt-get has a commandline switch to behave that way, too:
"apt-get --with-new-pkgs upgrade"

Ok, I also understand the latter reasoning. But doesn't that mean that
there are thing "apt-get dist-upgrade" can't/doesn't solve? Or is this
step only necessary if "apt-get dist-upgrade" didn't solve everything,
e.g. with 3rd-party repos or such?

Hrm, ok. I probably can't say too many things about that as I'm one of
the "dist-upgrade in many little steps with aptitude" guy and hence
don't care a lot about default dependency resolutions.
