As far as I understand, this ticket is about changing the lang attribute. Changing the subdomain is a separate task, isn't it?
I took part in the discussion to standardize the -simple subtag and would love to see more adoption. Wikipedia could be an important step e.g. to get assitive technology vendors to add support. So I would very much like to see this issue fixed. Is there anything I can do to help?
