A removal could theoretical cause the installation of another
package. AFAIK the resolver in APT can take updates into account to
satisfy dependents of a to be removed package. This could e.g. happen if
the maintainer merges a package into another one and the user wants to
remove the old version, not having the updated merged package
installed.

Surely it's a corner case, but one that should not be missed.
