If a package is upgraded, surely a user would want any new packages
to be installed if they are required to satisfy dependencies. apt's
designed behaviour looks more sensible than apt-get's.
Not necessarily. Sometimes the dependencies get out of hand, like when a big project adopts a small utility and then decides that the entire project is a dependency for the tiny utility. It doesn't happen often, but it has happened to me. I like that apt-get upgrade updates everything else. If I decide I can stomach the other packages, I can always do a apt-get dist-upgrade and install them.
