What a disjointed writeup of a terrible idea. We only use git _because_ its history is a graph rather than a sequence, freeing us from the necessity to ever acquire locks on fellow humans. There's a reason git.git never does anything like this, despite the history being completely constructed by Junio Hamano (who applies patches with git am, rather than taking a set of commits from someone's remote as is typical on Github). A clean history full of useful information looks like git.git's history: nonlinear.
