You've just described the use case for a local certification.

Certifications come in two basic varieties: public and private.  A
public certification is intended as an announcement to the world: "Hey,
world!  I am [name] and I vouch for this certificate!"

If people want to make public pronouncements of social relationship, why
in the world would you want to deploy a technology that makes it
difficult to discover this social relationship?

This doesn't make any sense to me.  Quite possibly I have completely
misunderstood what you're arguing.
