I don't think we should change the default behavior. The point is to
give the user a way to go back to an old version, should they wish to.
Consider this scenario:
ImageMagick 6.4.4-10_0 is installed
User types "sudo port upgrade ImageMagick" and upgrades to 6.4.5-0_0
6.4.4-10_0 is deactivated and remains installed
User discovers 6.4.5-0_0 has a fatal flaw  and he needs to go back
No problem: "sudo port deactivate ImageMagick @6.4.5-0_0 && sudo port
activate ImageMagick @6.4.4-10_0"
If we change the behavior so that the old version is automatically
uninstalled, the user has to use a rather complicated procedure to
install the older version again, which is documented here:
Not to mention the fact that reinstalling the old version may take
considerable time to compile, whereas simply activating an already-
installed version is quick.
I would rather use up a little more of the user's somewhat cheap disk
space and make them type one additional command to reclaim it, and
give the user this easy way to undo an upgrade, than make the user go
through a whole set of steps to do so. If the user wants to knowingly
take that risk, he can use the -u switch when upgrading.
