What, and re-do every commit after the one that added such material?
And somehow find every tarball that was shipped with the material, and
make them go away? Please don't bring straw-man arguments.

No amount of review will prevent human error at the point of the final
push. Yeah, Bruce was probably unreasonably sloppy about this particular
commit, but to imagine that we can get the error rate to exactly zero
is hopeless. That's what "git revert" is for.
