Just a thought -- but if JSONPath can let us query the provided and required APIs w/o unmarshaling the entire CSV, should we use it to more accurately verify the content of the bundle fields?

(this question shouldn't block the PR)

I was thinking that if the grpc has any provide/required apis, we just trust that (gives us more freedom on the side of the registry going forward).

// fallback to csv parsing

return nil, fmt.Errorf("couldn't parse bundle")
