I thought Linus had mostly worked on the inner workings of Git (the "plumbing"). These are awesome. But the CLI part is not straightforward at all. I keep seeing people new to Git having great pain to use it.

So, if some new folks come up and expose clearer CLI concepts than Git does, then I completely agree with their initiative. On top of that, if it remains compatible with existing Git repositories, then I will surely give it a try and maybe use it regularly.
