That doesn't mean that *You* can add a Signed-off-by:

Nobody can certify sign-off for anybody else. Read the sign-off rules:
you can add your *own* sign-off if the rules hold, but you can't sign
off for somebody else.

The "Co-developed-by: must be immediately followed by a
Signed-off-by:" thing only means that if there are multiple
developers, then ALL DEVELOPERS MUST SIGN OFF.

It absolutely does *NOT* mean that you adding a Co-developed-by means
that you then add a Signed-off-by.

That's like faking somebody else's signature on some paperwork. Never
do that either, and it's hopefully obvious why.
