A new region has been added to all Flex Templates grids called the "front and index bottom container." This grid inherits from the front page to the index pages, but does not show on asset pages (such as articles).

Front and Index region

This unique region allows items to be added to front and index pages without requiring the extra work of changing inheritance rules on the sub pages.

An example of this would be a third-party widget or specialty block that works great on the front page may not be something you want on articles.
