[2022] Why won't they add Ashe to the support role?

Honestly of all the champs they've just currently added to other positions like Riven and Diana for jungle and Veig now in support role, how tf have they not yet added Ashe?? Since day 1, I already thought that Ashe would be perfect in support roles.

Her passive slows enemies which is super annoying especially in late-game. Her W gets even more annoying than her passive considering when you level up high enough, you can just spam her W on absolute anybody since I'm pretty sure it only has a 2 second cooldown. Her passive is also enhanced when using Q. Her E can be useful when your team's in need of vision, which I usually use when there's no wards on baron/rh/drag most of the time or when I just use it to light up the usual places where everybody would put their wards down. And most of all, I absolutely can't forget that you can even control her ult in Wild Rift, whereas in PC you can't control it all since it just works like a regular Ez/Jinx ult there.

Her kit definitely gives off more support vibes than ADC vibes so I've been wondering, of all the champs that have been getting added/switched to the other champ role pools, why hasn't Ashe been added to the supp pool???
