Pharo and Squeak had a DVCS called Monticello that integrated with the system much better than git, but they abandoned it in favor of git, primarily so they could use github, expecting it would raise their profile amongst developers (also the VM was already developed there). The end result was the method-level modification history, including timestamps and authorship info, was lost, since it didn't fit into git's model of treating everything as text files or blobs.

Git is also much more confusing than Monticello.
