You mean the text on covert channels? I always thought the way to
avoid covert channels was to use implementations that didn't have
them. In particularly, ECDSA has a covert channel which cannot be
closed, and so does OAEP signature.

It's not wrong, just incredibly weird that this would be considered
worth adding to the draft.
