Could you please provide some more info on the change? What is wrong with the current name and is there someone else who can confirm that this a better name? All the Chinese locales should at least follow the same format for the name.

Chinese locales such as zh_TW and zh_CN are 繁體中文 and 简体中文 respectively. The locale zh_HK is not initiated by me, and there is an extra word 版 and an extra tab inside the locale name when I look through the source code, the former of which looks awkward when put together with other Chinese locales and when it is showing up in some sites. The locale founder did not pay attention to the naming when initiating this locale.
For example, it exists a phrase for zh-TW 台灣正體中文版, which is Taiwan Traditional Chinese version when translated into English, but for zh-HK it turns out to be 香港中文版版, which looks awkward.
Hence I would like to have it be consistent.
