I just rewrote most of this page and reorganized most of its content. Given that the scope of my changes was so large, I think it would be best to translate it all as if it were a new page. I wasn't sure how to make that happen, but that is why I removed all the translate markup when I made my recent revision. Apologies if that was the wrong way to proceed; I can try to fix it if that is the case. See https://phabricator.wikimedia.org/T293773#7886221 for more background info.
