Speed _is_ important, of course. But the user only benefits from speed, he doesn't have to manipulate it explicitely. I may be repeating myself, but "diff --cached" doesn't mean "diff using the stat-cache", it means "diff using the cached _content_", which is really unrelated from the stat-cache.

Mercurial also has fast diff (perhaps a bit slower that git, but same order of magnitude), and has no user-visible index.
