I believe this is true, but reading through a description of how the underlying persistence model works was for me a revelatory experience. This was presented together with a description of the precise problem git was designed to solve in the O'Reilly book, Version Control with Git. It seemed to be a problem solved in every particular -- an exact solution, that rarest of all things. I did struggle with git before I read about it, which is why I picked up the book in the first place. Since then I have convinced myself that any failures with git are due to my own deficiencies and not its, but my tasks with git are far from exotic; I rarely encounter any difficulties.
The value in the software is not so much the UX, which I consider acceptable (at least with aliases), but in the underlying data model. For me, it is a tool of daily use, and so the knowledge required to use it is a trivial investment. If we were discussing something other than a command-line tool, I think I might be more amenable to the argument that a simpler UX is a better one. With the CLI though, you pretty much need to know what you're doing before you attempt to do it, and any problems with the process are rarely considered UX issues.
