I was not aware of any open source implementations until John Henderson
from Energy Web proved me wrong. To gather the data and research that you
need for the traceability api implementers, I'd suggest running a survey.

You may have incorrect and incomplete data that could lead to faulty
assumptions. CHAPI Playground is focused on creating a seamless experience
for receiving verifiable credentials and presenting those credentials to be
verified. Additionally, it allows for different Issuer and Verifier
Backends to be connected to the site as long as they are compliant with
vc-api. It's focused on a specific lifecycle of a credential.

The prove endpoint was not a requirement to prove out the lifecycle.
The prove endpoint was not raised by implementers as a solution to a
problem they had within CHAPI Playground.

In short, the prove endpoint was not relevant for this specific use case.
It should not be misconstrued as not relevant for *all* use cases.
