Hello Andre, I think you should move the inventory you posted on en.wiki to a subpage of https://www.mediawiki.org/wiki/Bugzilla so that it can be edited and discussed on talk. "Current situation" seems almost complete; on the contrary, the "Proposed pages" section is completely unclear to me, you should probably clarify which bullets make a page and on what wiki (which depends on the audience). When there is a plan, discussion on en.wiki will be appropriate only for the pages there which will need to be merged/interwiki-redirected elsewhere (Meta, I assume).
