This looks great. Filling in the gaps. :-)
I'll add my rote recommendation to update the existing pages (even if that involves a complete replacement), rather than starting new pages, because M:Grants:Learning patterns/Every new page starts off unwatched. E.g. https://www.mediawiki.org/w/index.php?title=OOjs_UI&action=info has 33 page watchers, and the subpages have fewer but still more-than-zero.
