Pronoun Trouble

doesn't AO3 already make sure clicking Uzumaki Naruto/Uchiha Sasuke goes to Uchiha Sasuke/Uzumaki Naruto because alphabetization?

also I feel like your vision of fanwork archive tagging and mine are not gonna get along? because while your examples of tags you don't want are definitely annoying and I'd be okay if they went away: here are the freeform tags on my novel-length, less the five that are not already AO3 canonical freeforms. I know this is too many but all of these are one or both of (1) something I want to be sure people can exclude from their search, or observe in the metadata and then avoid the work itself, if the described content distresses them (2) something I want to be sure people looking for this content can find my fic. which is to say, they facilitate searching, in the exact manner that "no cops at pride only aziraphale and his sword" equating for search purposes to "Queer Guardian Angel Aziraphale (Good Omens)" does.

Alternate Universe - Canon Divergence, Akumatized Marinette Dupain-Cheng | Ladybug, Identity Reveal, Emotional Hurt/Comfort, Romantic Angst, Angst with a Happy Ending, Character Death, Temporary Character Death, Suicidal Ideation, Fire, Lies, Truth Spells, Unreliable Narrator, Queer Themes, Puns & Word Play, Autistic Marinette Dupain-Cheng | Ladybug, ADHD Marinette Dupain-Cheng | Ladybug, Stressed Marinette Dupain-Cheng | Ladybug, Stubborn Marinette Dupain-Cheng | Ladybug, Autistic Adrien Agreste | Chat Noir, Adrien Agreste | Chat Noir Has Issues, Adrien Agreste | Chat Noir Needs a Hug, Nonbinary Alya Césaire | Rena Rouge, Angry Alya Césaire, Good Friend Nino Lahiffe, Badass Alix Kubdel, Chloé Bourgeois Redemption, Protective Kagami Tsurugi, Minor Chloé Bourgeois/Kagami Tsurugi, Minor Alya Césaire/Nino Lahiffe, Minor Juleka Couffaine/Rose Lavillant, Gabriel Agreste | Hawk Moth is an Asshole, Emilie Agreste Lives, Lila Rossi's Lies Are Exposed, Miraculous History, Inspired by Fanart, Podfic Welcome, Fanart Welcome

(the relationship and character fields only have the four most important of each, plus the character field has Miraculous Ladybug Ensemble. 'cause people looking for fics that are predominantly Chloé/Kagami will be disappointed in this fic, but their relationship is part of a key subplot.)

under your proposed schema I think I'd have a plot tags field looking like

Alternate Universe - Canon Divergence, Identity Reveal, Emotional Hurt/Comfort, Romantic Angst, Angst with a Happy Ending, Character Death, Temporary Character Death, Suicidal Ideation, Fire, Lies, Truth Spells, Unreliable Narrator, Queer Themes, Puns & Word Play

if that much, since you explicitly don't want the army of wranglers who would need to approve or deny ones like "Akumatized Marinette Dupain-Cheng | Ladybug", "Chloé Bourgeois Redemption", or "Lila Rossi's Lies Are Exposed". I think it's a plus that people looking for fics with one or another of those three plot elements, or unwilling to read fics with one or another of those three plot elements, can search by those, or search by not those, or observe them in the work's metadata and choose whether or not to click the work. and without being able to search on "Podfic Welcome", podficcers looking for fanfics they don't have to explicitly ask permission before podficcing would have a difficult time finding my stuff.

I'm not sure how we keep the parts I really like about AO3 freeform tags without also keeping the tag wranglers and both keeping and patiently ignoring the rambling, story-unimportant, never-to-be-wrangled freeform tags.
