Unitframe class color not implemented yet in 2020?

Please, can we just make this feature a thing in the possible patches/future?

I just don’t want to download any kind of addon and wait for the uploader to update the addon because it’s bugged.

The Unitframe class colors should be a feature in the game without addons, whenever you target a player instead of a green/blue frame you would see the class color just like how party/raid works.

Please.

You mean color the Target frame by class? The trend is they take out more options than they add, so it seems unlikely
