On my Ubuntu machines, `man rev` indicates that it came with a package called util-linux, so it seems like it might actually considered even more essential than coreutils. Funny enough, that manpage lists `tac` under its "See Also" section, so maybe these two packages are tied together at the hip. You describe a really clever use case for rev. On the surface, my intuition was that reversing, cutting, and reversing again wouldn't work if you had escape sequences, but I suppose that's a moot point with cut!
