But why should each developer need to do that on each system they use?

The whole point of this tool is to add a common set of things on top of git.

I don't see why each developer should. I'm perfectly fine with commands as they are by default.

I'm just saying that if your problem is that you need to enter multiple commands instead of one, then instead of new VCS you may as well just put a config file in your home dir.

This isn't a new VCs though, its a layer on top of git.

You can still use all git commands.
