It adds additional strong restrictions on the order in which packages
must be upgraded. Too many such restrictions and there might not be a
way to upgrade at all. Somewhere before that you (via apt/aptitutde/...)
get the effect that you have to temporarily remove packages to upgrade.
The less restrictions there are on the order the easier it is to
upgrade.
