deprecate extra

Despite its definition, currently extra is being used for a myriad different things: unnamed background characters, pov hands, people, crowd etc. Even characters which have a chartag, such as justice_task_force_member_(blue_archive), get extra as a padding tag.

The purpose of this tag was doomed from the start, because it's one of those "put everything you don't know how to tag into it" tags, and it doesn't even make that much sense: if we can tag OCs even without knowing their names, by giving them a temporary tag such as weno's_blonde_original_character or red-haired_warrior_(gurimjang), then nothing's stopping us from adopting a similar standard for visually distinct unnamed background characters or archetypes from proper series.

For this reason, I'm proposing the deprecation of this tag and rewriting of the wiki to include guidelines and instructions for the creation of character tags in cases like these.

Just to double-emphasize how doomed from the start the tag was, it was already being used as a padding tag on characters that had already been given chartags, such as Wakaouji Ichigo and Celestial Being Extra, back when it was created.

The bulk update request #20637 (forum #257569) has been approved by @evazion.

Now that the tag is deprecated, the proposed rewriting of the wiki to include guidelines and instructions for character tag creation in these contexts should occur. Similarly, we should consider what to do with the info currently present in the wiki, mainly the Other Names. Can the Other Names listed be placed in other wikis, or are they too awkward for use?

A major purpose of extra was finding art that focuses on characters that were originally designed as random background characters in the media they came from. What will be the replacement for that? It was particularly useful for series like K-On!, where there were a lot of characters designed with non-speaking roles.

A tag name like "untagged character" might at least allow for collecting some nameless background characters without it added to easily taggable characters as padding. This has the problem that anyone can decide to create a made-up chartag like Celestial Being Extra and 'remove' a character from the tag, but excluding some characters is better than having a dumping ground of a tag with arbitrary criteria.

On that note, I feel like it's pretty subjective just how minor a character is (for example, some people might think Wakaouji Ichigo is not minor because she has a name, others might argue Koakuma and Lily White are minor because they have no dialogue in their original game). Thusly the broader concept would be better served by pools in the first place. This would also allow for smaller, copyright-specific pools that could be kept tidy by interested individuals.

The name "untagged character" sounds like it'd just end up mistaken for character request, and will end up a dumping ground of posts where they want someone else to tag the missing untagged characters of.
