WRT the reasoning I have a gut level feeling its not technically solvable so I'm going for an abstract proof that its equivalent to a known existing unsolvable philosophical debate, therefore any mention of technical problems or feature list of git is bike shedding because its provably unsolvable at a higher level. So if the answer to the philosophical question is two opposing camps, and we have the source code revision control solution for one pole, then all we need to do is find the opposite pole and then ask the two never to merge (oh the extended pun..) groups, to realize the other side exists and please be civil with each other, etc. That could save a lot of wasted effort. Clearly the equivalent of methodically twisting Python into Perl one little bit at a time isn't going to make anyone on any side happy, or vice versa.
