Ah yes, simplicity. That easily quantifiable value of a singular dimension, whose definition we all agree upon.
Finally someone agrees with me! Yey!
Kidding aside, git-merge is simpler because you only need to know 6 commands: co, add, commit, push, pull and merge. I believe that these will help you achieve everything you need with git.
I’ve seen histories full of arbitrary fork points and merge commits that are definitely not simple.
Imagine what these people would do with a tool like rebase going wrong
