My point was that if any mapper is using data under a licence that requires attribution, then they can only do so if the required attribution is given on either https://www.openstreetmap.org/copyright or https://wiki.openstreetmap.org/wiki/Contributors . Otherwise OSM would be violating that licence by distributing a derived work without the attribution. So assuming permission to use the South Gloucestershire data is conditional on some attribution (which is the case for e.g. the OGL) then it needs to be listed as a source on the contributors page, with the appropriate attribution given. (Separately, I think it's also important from a community verification point of view that sources and licences are documented, so other mappers can check we have the necessary rights to use any claimed sources, and there is evidence if anyone challenges our use of particular data.)
