Benefits (why should this be implemented?):
@Aklapper Because I got someone to (temporarily) give me admin (and importer) there. Are you suggesting that test2wiki should not be used?
Don't know as I don't know what you plan to do. See https://wikitech.wikimedia.org/wiki/Test2.wikipedia.org and https://wikitech.wikimedia.org/wiki/Test.wikipedia.org for purposes.
In any case, I suggest to initially explain things and provide sufficient and complete context, as already requested several times. The repeated back-and-forth in conversations is not a good use of anyone's time.
Please follow the instruction shown on https://test2.wikipedia.org/wiki/Special:Upload, there's nothing to do here.
