Git was really useful because it allowed decentralization but didn’t require it like CVS or SVN. It catered to the “just clone the repo and create a new branch when you hop on the airline and push updates to origin when you land” model. But it’s really unusual that people really want a hugely distributed model. Typically, people want to go to The Blessed Repo and get The Blessed Code. For example, Linus’s got kernel tree is more important than everyone else’s clone.
