Mostly agreed. I have some notion that a commit "should" be a well-defined change in terms of program behavior, so if I can develop a feature in actual stages, I like to make separate commits. That's often the case with complex features. Multiple commits can be confusing too, when commit messages aren't good, so I think making coherent changes is a problem beyond commit frequency...
