Yeah, exactly. Radicle doing it this way, Fossil another - see here why that is a problem: https://xkcd.com/927/
And Fossil is an entirely different VCS. What’s the alternative? That at least N projects cooperate and agree on a common design before they do the implementation? (Then maybe someone can complain about design-by-committee.)
The alternative to that would be the git project itself coming up with an implementation. They have reasonable experience working with the Kernel, and the creation of git itself seems to have worked reasonably well -- although I'm not sure I would want to use something Linus considers ergonomic :)
