You can commit code that doesn't compile onto a feature branch so people can see what you're up to, I guess, but I don't see that helping with bisecting later, and I wouldn't expect the commit messages to be useful.

To be clear, my typical approach is certainly to commit every time I return to a working state. But in more experimental modes, I often reach that the long-way-around and have ended up with multiple semantic changes I wish to break apart for study.

Unless I'm missing something and Fossil has gained the ability to cherry-pick selective lines from a commit.
