I’d rather not hack my process around the deficiencies of someone else’s poor UI choices. As long as the data is stored in a powerful, structured format, you can serve that up in any way that’s sensible to you with `git log` and other shell friends.

That's your prerogative, but a) conventions are not "hacks", and b) the main benefit of CCs are their visibility. If most code forge web UIs and standalone tools don't make this information visible, it's not of much use. `git log` is just one way to surface this information, and "shell friends" can also make "poor UI choices".
