Perhaps, but a sign-off is also a recognition that the
patch was passed-through by individuals

Effectively, there's no real difference.

"Co-developed-by:" is just another word for "Authored-by:"
where multiple "Authorship" is the thing being notated.

Is it really important to specify things like 75% / 25%
authorship crediting?

I don't really care about attribution so the concept is
not particularly valuable to me.
