In my mind, Jetpack is a single plugin with multiple "modules", or put differently a plugin pack - a collection of a number of plugins all working together to achieve a similar goal (in this sense it's to minimize the time it takes you to manage your site on a day-to-day basis). You have the ability to go in and de-activate what you do not want to use. I believe this is the future of plugin development. Some plugins do this with downloadable modules (edd/gravity forms add-ons). These just come pre-packaged with the ability to activate, instead of download, what you want to use.
