There is no good reason to keep passing around the url parameter when its contained within urldata (ud). This is left around due to legacy reasons, some functions take it, some don't and its time to cleanup. This is fetcher internal API, there are a tiny number of external users of the internal API (buildhistory and distrodata) which can be fixed up after this change.
