With the addition of the GFE Collection Bundle being the bundle submitted via the gfe-submit operation (https://jira.hl7.org/browse/FHIR-44951), it is no longer needed for the claim resources to identify the submitter. In the older GFE bundle, all provider resources were at the entry level of the bundle, and therefore the submitter needed to be identified. With the GFE Collection Bundle, the only provider at the top bundle level is the submitter.
