The default blocks in Gutenberg blocks includes a “group” block. Atomic Blocks, Qodeblock and Stackable added their own called “container”. The point of these “parent” blocks is to add a container around a bunch of nested blocks within it. Suppose, for example, you have four blocks that always go together — a header, a paragraph of text, an image, and some links. You could put those four inside a block, and then if you want to move them around a page, you just move the big container block, and all of those sub-blocks / child blocks will move at once. They stay together. Alternatively, where it becomes really useful is if you put the four child blocks in a reusable group block, say for example instructions on how to do something that you frequently refer to in your posts, and you can dump that block in anytime you need it.
