This means you may ended after some time to have quite a lot Office 365 Groups while they are not used anymore as tied to a project or any other temporary need.
Good new, you can now set an expiration time for Office 365 Groups, meaning they will be removed automatically at the expiration date. Currently in preview.
Don’t worry, when the time comes, owner(s) of the expired Office 365 Groups will be notified and if they still need it, the Office 365 Groups will not be deleted.
Also, in addition to that, remember you still have the possibility to recover deleted Office 365 Groups (see http://blog.hametbenoit.info/Lists/Posts/ViewPost.aspx?ID=855)
