Not the person you're replying to, but years ago Metux used to send PRs to a different project that I maintain. He was difficult to work with, insisted that his way was the right way when I wanted something else, and his code quality was usually middling at best. Some of his PRs were of the annoying "tidy this up" form, where it felt like someone who just wanted more commits in a repo and lines in `git blame`.
I hope his xlibre project is successful, but my opinion of the project is certainly tainted by my past interactions with him.
