1: I thought the proposal already was accepted, but you also did mention that for organisms it would be harder to group by taxonomy due to most of the organisms being distinct enough between species and genera to warrant their own profile (so I'm not sure if it's possible to then group the more similar organisms under common higher taxonomic ranks like family, order, etc because you also mentioned the issue of them being considered composites)
Other categories that may require restructuring would be:
Weapons by grouping into weapon role/type/usage entries (such as Sniper Rifles, Machine Guns, Mortars, etc) with individual most notable/highest-tier record-setting (by VSBW Powers And Stats/Abilities standards or real-world standards) weapon details and stats being stated in the Powers And Stats/Abilities section of the weapon role/type/usage entries
(^due to the current layout overly focusing on individual weapons or species, many of them being the same type of weapon or using the same caliber and thus being of nearly equal AP).
Natural and cosmic phenomena by grouping as per type of phenomena (such as types of natural disasters, particularly earthquakes and volcanic eruptions, instead of listing individual cases of disasters).
2 and 3: I'm not asking to incorporate the category system into VSBW, I'm asking to add entries from the Wikipedia categories and lists and articles within the Wikipedia categories to the Real World verse page.
Specifically, if we're narrowing it down:
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
en.wikipedia.org
Possibly worth considering adding as new entries/categories in the Real World verse page:
en.wikipedia.org
en.wikipedia.org
That being said, not everyone here has seen the proposals so while the staff (Ant, Medeus, etc) are convinced, I do not know for sure if everyone else responsible for editing the Real World verse page is OK with these proposals of restructuring the entries and having to change/move pages to fit the proposal's suggestions (like Spears to Polearms, AKM, AK-12, etc to Assault Rifles, SCAR, G3, etc to Battle Rifles, etc) and subsequently add/change links to redirect to the new updated/moved pages.
