We are working on FHIR questionnaires and I wonder if there is already a library with definitions of FHIR questionnaires. I found GCS example https://www.hl7.org/fhir/questionnaire-example-gcs.html. Is there any place where I can find wider set of such definitions? If not, is it planned to be somehow created / maintained? I can see having such set published as something valuable for the community.
