Nolan, I must say im agree with you. Add-ins are not that welcomed in larger companies.
But add-ins are also a great way to test and try the useful tools before actually launch them onto the applications. Like "Power Query" is a very good example, they tested it with couple of versions then found "right, people really do like this." Then putting them into the application to be native.
Unlike Power Query, I thought the Map add-in on Outlook were a powerful tool too, it helps users to track and predict the route between places, but it never became common I believed.
