I saw that they use OpenVPN protocol[1], then I stopped reading other things. Although the encrypted connections can not be decrypted, the OpenVPN protocol is easy to be detected and banned in some highly censored network.
I recommends the shadowsocks protocol[2] which I used in the censored network, which is hard to be detected and decrypted.
As for PR workflow, it will be hopefully. There's a discussion[1] to replace the Alioth[2] with Pagure[3], which has a similar workflow with Github. Maybe the Pagure is not the final decision, but it will be a modern platform that's easy for contributors.
A community is not about how many people have permission to write the main repository. Linux kernel is the example. Linus is only one who has permission to write the mainline tree.
I suggest you looking at Wubi input method[1] which is widely used in China for more than 20 years. My first impression of your method is just the same as Wubi.
The reason why Pinyin input method is more popular, I guess, is that Wubi is too hard to learn which need remember a lot of rules.
But quoted from Wikipedia,
> it is true that Wubi is extremely fast when used by an experienced typist.
So Wubi is still very popular among those who need to type a lot of characters.
