There is an expectations vs actual behaviour problem with excludes in
package-based systems. Apple and Windows updates are feature-based
(they can touch multiple applications at once to chage their behaviour
together) while our distro updates are package-based. This leads to
excluding being only efective until another package pulls the ignored
one via its deps. So expected is "I ignored foo-2.1 so it's still
foo-2.0" while actual is "I ignored foo-2.1 but bar-0.0.2 pulled
foo-2.1 so it got upgraded anyway."
