I'd love to dig into Pijul but sadly it's AGPL. Just looking at the code effectively taints me as a developer who works tangentially to VCS - it could be argued that my work is derivative and thus needs to be AGPLed. The viral nature of the license then creates an existential legal risk to my employer.
Until 1997, forking a project was considered a tragedy. I think things have improved since then :-).
