to be fair, if you just want to improve the UX for yourself you can totally have a fork, make your changes, and use it on your own machines when talking to github or whatever other git repository. Now getting someone else to accept your changes might be harder, but that's what happens when you try to change a tool so many people use, especially one with a lot of history. Maintaining a fork is literally one of the things git was designed to make feasible after all.
