What is the purpose of Radio Group Orientation?

[Alek99]

Hello, based on the themes and primitive docs this prop is never used I would assume it would be to orient that group horizontally or vertically but in the docs, the items are just put in a flex?

As seen below shouldn't it just have the root as orientation='vertical'?

all props in radix are for functionality or a11y purposes only and never for controlling the styling/layout of a component. it is up to you to style the component vertically or horizontally based on the orientation you pass. the orientation prop simply aids screen readers.

@Alek99 specifically in this case, it helps setting up the right arrow keys for keyboard navigation.
