Are you using Context to manage your block layout? Then you definitely had a case where you wanted to place two (three or more) blocks next to each other and maybe one block bellow. Or maybe you had multiple blocks in one region and one of them had to be displayed in full width while others had some container around them. In both cases, you probably created additional regions or created a custom block where you group other blocks.

Context groups add an option to add groups to your reaction in a context. Context group creates a wrapper for your blocks, to which you can add classes, to help you with styling on the front end.
