When using vc.js, I have observed that if the pre-configured contexts are not loaded, I am unable to even sign/verify the credential. I might have to come up with our own processing code to circumvent this issue.

David - in that model, does that mean that you ignore all contexts that you don't have "pre-configured"?  Are they at least properly stored and forwarded, as required?

    Hi Anil
    I can assure you that JSON-LD processing is not needed in order to
    implement a VC eco-system. JSON processing is all that is needed, along
    with pre-configured @context definitions
    Kind regards
