i think this should be deprecated (not rewritten to Go and a deprecation notice added to the perl response) as you should be fetching the regions for a division like GET /regions?divisionId=x (but may need to check that the divisionId query param is available on the regions endpoint)

+1 on deprecation as long as the query param works
