You are correct here — I've not been sufficiently emphasizing an
important aspect of Gordian Envelopes is that they are not solely for
point-to-point, but also data-at-rest. Though there are many use cases
for Gordian Envelopes beyond credentials, some of our communities'
pressing requirements for persistent credentials mean that they may be
permanently stored for a long time.

One use case for Gordian Envelopes really exemplifies this, the
educational credentials use case:

A school issues a student a credential, which in turn, they use to get
a job, which in turn is used by the employer to prove that they have
the personnel to make a bid, and then contractor uses it for
insurance. In another chain of holders, the subject got a loan for the
education, the school needs to prove to an approval body that student
loans result in jobs.

In all of these, the many "holders" of the credential have different
requirements, and the whole chain risks the subject's privacy.
