We now know that keyword expansion is idiotic and have moved past it.
The worst ones are the ones that expand the log messages, when they are implemented in such a way that it becomes permanent.
A wall of short commit messages condensed into a block comment don't help anyone understand anything, without the actual changes to refer to.
Keywords are supposed to help someone who works outside of the context of the version control, but that's ironically the person who is trying to apply a patch that is failing because of the expanded cruft, whereas the person working in the version control system may have a way to do the merge on unexpanded artifacts.
