As you say it's already happening for project where all the documentation is not in English. So what's wrong if the language also is not in English? Can you not imagine that some projects don't care whether you specifically can contribute or not? It's not the first language not in English actually, WLanguage for example from WinDev can be written in English, French or Chinese.
