Caret direction is certainly a feature of caret, it is required for full control of a caret. Here is one old example of caret API: , GetCaretDirection() is there.

caretPosition in CSSOM is just a position. The position is defined in same terms as Range (which BTW has similar issues with ambiguous positions, but chooses simplicity).

What is the use case when it is important in *CSSOM* to have caret direction?

In case we actually find the reason to have caret direction in CSSOM, I can suggest

 caretPosition.direction = "forward" | "backward" | "undefined";

(direction is logical, "forward" is direction of traversal of DOM tree towards from start to end)
