Since Add/Remove is currently incapable of installing updates, and therefore using Add/Remove doesn't mean you've decided to defer updates, it would be nice to exclude use of Add/Remove from resetting the 7-day timer.
Since installing or uninstalling applications is not usually a frequent task, though, I don't think this is a hugely important bug. (Bug 351484 is probably more important, for example.)
