Who recommends it (apart from CE?).  I've seen it warned about in a number of
places, and I recommend (strongly) against it in my (still in-progress) book.
It's the most dangerous encryption mode since RC4.

More specifically, it's RC4 all over again.  There's a reason why that was
dropped almost everywhere, for example the SDL explicitly bans it, and there's
even a Visual Studio tool that scans your code and complains about its use.
