Yes, that's the intended behavior. The purpose of the
configuration-table feature is to dump data that is needed for an
extension to operate properly --- for instance postgis has some
auxiliary tables that are best treated as part of the schema. If you
think the contents of a table are not effectively schema information,
then you shouldn't mark it as pg_extension_config_dump.

What tests were those exactly? I'm not aware of any agreed changes in
this area.
