Translation issue

From what I read on Polyglot, it’s not good to remove .po.mo files if the plugin is not fully translated. From the list you give, there’s not a single language that has reached 100%. Moreover, I believe this idea of “auto-translation” sucks 🙂 I have already used plugins with such feature, and it really sucks believe me. There are often translations done by some illiterate person, and the option of doing your own translation with .po.mo is always the best. I have no idea why WP is going this direction.
