Unlike translations to other languages, which are updated by the translatewiki bot along with adding translators to the author field in the files, the en and qqq files are created manually and without documenting the authors.
I wrote a bot that fills in the file's authors based on the file's git history.
I think it would be nice if it ran every few months (for example, before each version release).
I'd be happy to hear your thoughts on this.
