From the definition of Key:name, "The primary name: in general, the most prominent signposted name or the most common name in the local language(s)." 
Despite the gazetted name remaining as the "official" name, the station's signposted name is "Wattle Glen". You can see in the surrounding area, including that of the suburb is also "Wattle Glen". The gazetted name does not match what is used in reality, and we map what exists in reality, not a legal database. Why is this even a discussion? `name` is not what is considered official; it's what's prominent, most used, and locally recognised – which is what is signposted.
I suggest you choose a better hill to die on before you get suspended by the DWG over this pointless edit war.
