Lots of the value for me is in well written commit message bodies. Especially if I have written them since when someone asks me how something works or why it's written that way I can read the commit body and explain it to them/refer them to the message (otherwise my answer is, I don't remember!) Additionally if you choose your changes well and don't squash commits it can be a good guide to what else touches the thing I'm looking at.
