Even though the major use for MSM is all about language variants, there are different use cases we can serve using the capability. For example, we had a case where the help content of the brand is 'somewhat' same between their consumer brand as well as enterprise brand. There are certain sections of the help area that is different, but most of the areas the same.
So the consumer brand help content was the blueprint and enterprise help content was the live copy. They both lived under their own content trees and locks where provided where we didn't want the sync.
This is not an XF livecopy use case but a MSM use case but capability is very similar
