It isn't true the proposal isn't recognized by anyone and more importantly being an expert and a professional on the matter is itself a source of authority.

Furthermore, even admitting recognition as the only criteria to write toponyms, which can be very error prone and biased, particularly for languages representing a minority in a State, you should justify your changes instead of simply dismounting mine. I justified the change with an authoritative source, please make a counter argument or an argument at all on how you think it should be written.
