We raised the issue of a lack of notifications for removed plugins like this a while ago, unfortunately it has been three years since it was indicated that is was being worked on and it still hasn't been resolved.
We have added listings for Breadcrumbs EZ (breadcrumbs-ez) and Enable Google Analytics (enable-google-analytics) to one of one our plugins that warns about this type of thing and will be adding it to the other plugin shortly. If someone can let us know what the other plugins were so that we can add those as well, we would appreciate. If you don't want to post that information here, you can contact us directly through our website.
